Alligator

Mostly a snoozefest, but at least last 20 minutes are pretty awesome.

Surprisingly solid... The score is the main thing that betrays this as a B-movie, because it really is just budget Yamaha Jaws; but characterisation is decent and there's a genuine attempt to give a legitimate excuse for there to be a giant alligator hiding in the sewer. The editing is super tight, wasting no time in moving from beat to beat, and the practical effects are rather well done - I honestly wasn't sure sometimes whether I was looking at an animatronic or a real gator.
