My Top 5:

Halloween 2 (Zombie)
Batman & Robin
Alien vs Predator: Requiem
Film Socialisme
Jason X

We talking Blu-rays only or entire collection?

Entire collection:
Valentine: blind buy for $5 used. About $4.99 too high.

Blu-ray:
Sucker-Punch: another $5 blind buy. Not as bad as Valentine, but not far from it.

Sucker Punch is the first one that came to mind.

I like Sucker Punch...never understood the hate.

The worst movie in my collection is that 4th Indiana Jones film that came in the box set. Dude was like 70.

DVD - War of the Worlds (Spielberg)

I have very few BDs I don't like

BD- 2012 (Blind buy Target Exclusive)

Either the Omen Collection solely because it has to be the worst packaging ever.

Or Sucker Punch. Or Death Race 2000 (the shitty remake). Or Smokin' Aces 2.

This title was in my collection....for a day:

Probably the copy of Twilight I gave to my teen, who gave it back to me.

Return Of The Jedi
Indiana Jones And The Kingdom Of The Crystal Skull
Superman III , IV
Superman Returns
Rocky IV, V
Sucker Punch (probably...if I ever finish it)

Disliking more every time I watch them-
Temple Of Doom or Last Crusade
Batman ('89)
Batman Returns

Most stuff that I've hated I've gotten rid of quickly.

I buy what I like, why would I buy something I don't like?

If it comes in a boxed set with other films you do like...
Even though I hate them, I don't throw them away or try to sell just the disc in a plain envelope.

The other reason is a sour blind buy.

Off the top of my head:

Halloween V
Transformers
Anything I reviewed that I gave a "Skip It" rating

Movies in my collection that most people hate but I love:
Man of Steel
From Justin To Kelly
Grease 2
Batman and Robin (well, "love" might be a little strong for that one, but I don't hate it nearly as much as everyone else does.)

Day of the Dead 2: Contagium
Smokey and the Bandit Part 3

Entire collection.

Good Burger

I blind bought it way back when I first joined the site. People here were constantly talking about how it was such a great movie and should get the Criterion treatment. I was new then, so I didn't know that was all just a running joke with you guys. So I blind bought the damn thing.

The first thru sixth copies of Twilight I bought back when I was collecting every store exclusive.

Probably Godfather III. I watch every 5 or so years when I rewatch the first two hoping I will like it...and I never do. Only reason I have it is due to the set.

I don't generally buy movies that I don't have at least something I like about them.

Hip Hop Locos (2001)

It is the worst movie ever made. I'm keeping it around as a reminder whenever I think I just saw a bad movie I'll be like "but this isn't Hip Hop Locos bad":

Ender's Game.

Thought it was boring and won't bother in watching again. Good news is I got this on my birthday so I didn't waste my money on it.

It's not Citizen Kane, but a few winters back, the family and I were bored one evening so we spun it up on Netflix and actually had a fun time. It's silly, but it accepts that it's silly and runs with it.

Batman Returns
Batman & Robin
Halloween II (Zombie)
Indiana Jones and the Kingdom of the Crystal Skull- maybe hate is a strong word but I definitely don't like it as much as the first three films. I own three copies of it though. The Target exclusive DVD I bought originally, a copy of the single disc version my parents got me for Christmas (they didn't know I had bought it), and a copy with the Blu-ray collection.

In regards to DVD; quite a few purchases I hate now. When BD arrived I was more picky and basically bought only movies I really, really like.

My kids wanted to watch it based on friends at school recommending it. I'd never seen it so I figured fine, we'll watch it together. Spun it up on Netflix.

Remember the final scene of Hannibal where Ray Liotta is slowly losing all function? That's what watching Good Burger was like.

You should buy the Rifftrax for it. It will make the movie far more enjoyable to watch.

10,000 BC.

Looked like more dumb fun from the director of Independence Day, but it's absolutely unbearably boring.
