I wouldn't say hate, but there are a fair few I find overrated. 

Slumdog Millionaire

Lord of the Rings The Two Towers (it's funny, I love Fellowship and think Return is fine, but I still have a hard time watching the Two Towers). 

The Matrix

The Cabin in the Woods - the premise is clever, and the movie is funny, but it has as good or better reviews than The Exorcist or the Shining.

If we're going by critical praise, not many. Maybe Manhattan and Fanny and Alexander. Usually I'm in tune with the critical consensus.

If we're talking regular moviegoers then lots. The top 250 on IMDb has some very strange choices.

The Social Network
The English Patient
Crash
Mystic River

I have never liked the Lord of the Rings movies. I'm just really not a fan of high fantasy.

Hate is a strong word, but I really didn't see what was so great about Mad Max: Fury Road.

Fight Club: Soooo boring, and it had that "trying too hard to be edgy" feel to it.
The Matrix: Didn't find it to be that great, was just "ok" to me.
Frozen: Barely anything happens in this movie, I swear at least 80% of it is just climbing mountains during snowfall. Recent Disney movies have been getting a lot better thankfully.

Edit:

Boyhood - The concept itself is genius, but the movie was such a drag that I had to stop watching after a while, and it's also too long for it's own good.

Honestly I usually hate most movies that try too hard to be "philosophical" instead of telling a good story, they just end up being boring to me. I'm also not a fan of superhero movies, I don't know why they became such a big thing nowadays =P

Not really hate but...

Avatar - Mediocre film at best, being pretty doesn't make a film good....wasn't even that pretty.

Well most all huge Oscar winners or whatever award winners are usually the most boring pretentious movies ever made. So any of them.

But otherwise, what I find funny is that most movies that tend to get say a 75% or higher on RT, end up being what I would call popcorn movies. A movie that really is only good watching once. You enjoy watching it when you see it in theaters and it might serve as a good movie to mindlessly watch if ever on TV. But I find that when looking at all the movie's that I own that, the only ones that I end putting in to watch, or repurchase on new formats are movies that are like 50% or lower RT scores.

The way the action is shot and constructed puts 99% of films of past twenty years to shame.   Fury Road should be shown to all action film directors as a case study.  Too often these days we have shoddily constructed rapid edited shakey cam garbage to disguise the fact the actor cannot do action or that it isn't that visually interesting or exciting.

Maybe people didn't into the characters and story, but in terms of filming action set pieces Fury Road stands with the elite and makes so many other action films seem pedestrian.

A huge while back I tried to watch The Dark Knight (second film) but it was too long and I got bored so fast because nothing was really happening from what I remember. I don't even think I made it halfway through the movie.

Maybe if I were to watch it again now I would feel differently about it. I wouldn't say I hated it though, just at the time didn't understand why it was so critically acclaimed.
