Are there any critically acclaimed films that you found to be not that good? 

I personally disliked Big Hero 6 a good deal. I found that the story was too predictable, the characters felt two dimensional and bland, and in some places I can't tell whether it's the voice acting or the writing that's bad. I just don't understand how as many people like it as they do. But an opinion is an opinion, no matter how wrong you feel it is.

I can't think of one tbh.

Hmm Frozen probably

The Big Lebowski is that one film where I just don't understand everyone's love for it. I've watched it three times and I love the Coen Brothers, I just don't get it.

I was and still am expecting a lot of responses saying The Force Awakens. I saw a lot of threads on disliking the movie.

The Avengers. I didn't hate it by any means, nor did I really dislike it. I just found it really forgettable.

The Avengers, Lord of The Rings 1 and 3 (I liked 2), Shrek 2, Every Star Wars Movie ever, Every Star Trek Movie, Frozen,

Most movies in fact to be honest. im very picky with movies

Inception
Avatar
Star Wars
Avengers
Iron Man
Transformers
and so many more...

Okay, I'm going to stop now! Think I might start a war with all the movies I'm listing...

mad max.
Thought it was avg at best, and here everyone seems to love it.

Belle & Sebastien the movie is so predictable that I guessed the ending when I first went to see it at the theater right before the movie started, people started arguing with me saying that I already saw it, seriously, I've never seen a movie so full of clichés.

Also Frozen is a nice one, after beeing surprised by the gem that was Maleficent and hearing from a lot of people that Frozen was a masterpiece I got my hopes up only to find out that it was only another princess movie, something less, nothing more
