Meet The Spartans and Disaster movie are the only two films I can recall where I stopped watching within ten minutes. They weren't even "bad funny", it was basically "Hey look, a reference to another thing, aren't we clever even though this is about the 6th film that has done it?"
The second Transformers movie was appalling except for one scene, and the third film was just entirely crap.
I hated Stuart Little as a child, and I doubt my opinion will have changed much.
The Expendables 2. Oh God, it was so, so bad. I could accept the first for being a nice throwback to the old action movie days, but this one was basically them doing it again, but with even less charm and an even worse plot.

]Now, if they were to make a live-action film of something I love, like Death Note (which I'm fully aware they're making)
Making?
They have existed for years.
They are in some ways actually better, but in other ways, much, much worse.
