I would have been annoyed at this question had Alexandre Aja's excellent
Piranha remake not occurred!
I also thought that
My Bloody Valentine 3D was far better than I could ever have expected (with fine 3D effects too).
So...how about...
Squirm
Tremors
Braindead (flying viscera!)
an
Alien installment (3D Facehuggers, of course!)
The Birds (that is getting remade isn't it?)
