I haven't seen many 2013 movies, so can't make a top5. :D

2 best were Stak Trek Into Darkness and Now You See Me.

2 worst movies were Iron Man 3 and A Good Day To Die Hard.

Best:
-Monsters University.
-The Great Gatsby.
-The Physician.
-The Lone Ranger.
-Despicable Me 2.

Worst:
-Man of Steel.
-The Mortal Instruments: City of Bones. Shadowhunter Bach FTW.

I can't remember any other film that was released this year.

Out of the two films that were released in 2013 that I saw:
Best: Hobbit DoS.
Worst: Gravity.

Gravity isn't bad, if you ignore the "physics" in the film. It's not bad, but not superb.
Consider the physics however, and it ruins the film if you understand basic orbital mechanics. The plot line is completely bollocks. It doesn't work like that.

Best:

• Ironman 3
• Pacific Rim
• Warm Bodies
• Now You See Me
• The Internship

Worst:

• Pain & Gain
• Evil Dead
• The Colony
• The Heat
• This is the End

-note, of the ones i have seen.

Best:
-Hobbit: The desolation of Smaug
-Thor 2
-Insidious II
-Now You See Me
-The Hunger Games : Catching Fire

Worst
-Pacific Rim
-Ironman 3
-Elysium
-The Lone ranger
-The Mortal Instruments: City of Bones

1. A Field in England
2. The Counselor
3. Gravity
4. The Place Behind the Pines
5. Blue is the Warmest Color

As for worst, meh too many to name.

Best: The Hobbit Part 2, Star Trek Into Darkness, You're Next, Prisoners, The World's End, World War Z, Monsters University, This is the End, Now You See Me (WTF Ending, Didn't work though it was good), The Croods, Man of Steel, Wolverine, Frozen.

Meh: Kick Ass 2, Gravity.

Worst: Elysium, Despicable Me 2, The Host (MUST NEVER WATCH THIS AGAIN), Grown Ups 2, Thor: The Dark World (Rushed), After Earth, Iron Man 3, Riddick, Red 2, RIPD, The Lone Ranger, Turbo (Why does this exist), The Purge, GI Joe 2, Mortal Instruments: City of Shit, Paranoia, Machete kills to be on the big screen.

Lol, you really looked forward to Grown Ups 2? That was the thing that made me stop reading this list, sorry to say. The two best movies I saw this year were the Wolf of Wall Street and American Hustle. I also think that The secret life of walter mitty was above my expectations. The worst ones were Iron Man 3, Olympus has fallen, Lone Ranger and Elysium.

id just swap Star Trak and Fast and the Furious apart from that same list more or less

The Best:
The Conjuring
Evil Dead
Insidious: Chapter 2
Django Unchained
Despicable Me 2

The Worst:
After Earth
Jack the Giant Slayer
Pacific Rim
A Haunted House
I cant think of any others

Well the best would be so hard to choose, cause I saw a lot of great movies in 2013, but here's a handful of them:

There's not particular order, just a list.

The Best

• The Past
• Oblivion
• The Great Gatsby
• Gravity
• The Hobbit: The Desolation of Smaug
• Monsters University Yes, this one is extra, I know. just wanted an animation here.

The Worst:

• Riddick
• Open Grave
• Identity Thief
• After Earth As much as I love Will Smith, this one was just not good...
• White House Down

kaay It keeps putting 2 ones here I uno

(1)John Dies at the End

(2)Gods Behaving Badly

(3)Only God Forgives

(4)Thor :The Dark World

(5)Movie 43 (just b/c it did what it set out to do)

Worst:

5. Star Trek Into Darkness ( seriously? entertaining but a big FU to the Stat Trek Mentality. . . I love Bradbury)

6. Man of Steel

7. Monsters University

8. Riddick

9. G.I. Joe: Retaliation ( seriously ugh)

Now you see me

Switch StarTrek with Despicable Me 2, and i'll agree with your list.

I´m working in a Video Rental Store in Germany..

From what my customers said:

Worst:

1. Only God forgives
2. Gallowwalker
3. After Earth
4. Oblivion
5. The place beyond the pines

Best:

1. The Hobbit
2. Django - Unchained
3. Olympus has fallen
4. The Call
5. Identity Thief

Maybe some of them were in cinema 2012 but all started for rental in 2013....

There were many other good movies like: Now You see me, Evil Dead and so on..it´s hard to say =)

Best movies I watched: Django and Lone Ranger (most magazines said it was bad and it only got 33 good rviews from 140, but I loughed my a** off, Johnny Depp was great)....

I have not seen a lot of movies from 2013, like gravity, rush, riddick, insidious 2 etc... but maybe these:

• Conjuring
• Sinister (i saw it in 2013 /6 December 2012 Hungarian release date/)
• Trance
• Django (i saw it in 2013 /17 January 2013 Hungarian release date/)
• Dredd (i saw it in 2013 /10 January 2013 Hungarian release date/)

If it's not that good, why put it into a "worst" category, then? Talking, of course, about Star Trek Into Darkness.

Best and worst, in no particular order. Last year didn't really have any "wow" movies that I've watched so far... haven't watched a lot, granted, but the ones I watched weren't impressive.

Best:

• Star Trek Into Darkness: Nice Star Trek movie. Decent acting and plot. Pretty solid.
• World War Z: I wasn't expecting much of this movie... but turns out to be an enjoyable movie... full of zombies and whatnot. Not a masterpiece but certainly a good enough movie to sink 2hs into. Enjoyed seeing the various countries they showed in the movie, especially Israel.
• We're the Millers: A comedy with Jennifer Aniston? Red flag! I was expecting 0 of this movie, I watched it because I was bored but it turned out to be quite funny and entertaining... For what it is and for what it wants to be, this movie is ok.

Worst:

• Django Unchained: I hate Tarantino's movies. They are lame and so extremely boring... I really tried to like them... I just can't do it for the love of god.
• Oblivion: Although I don't think this movie was that bad, it can be a little bit tedious sometimes... It's not a bad movie, but could be a bit better.
• The Hangover Part III: It's what you'd expect from a Hangover movie, it's funny, but a little bit disappointing. Not as good as the previous 2.
• Parker: This is the kind of movie you expect from Jason Statham and Liam Neeson. It's entertaining enough though.
• Dark Skies: Now, the reason why this movie is here and not in the best is entirely because of the ending... I don't want to spoil though...
• Don Jon: The movie has a curious plot... but the acting my god... Joseph Gordon-Levitt and Scarlett Johansson as... I'm not even sure what... italian descendents? What.
• Kick-Ass 2: Huge disappointment. The first movie should sue this one for being so... boring.
