All right, well, I finished this thing.
I went into it totally ready to give it a fair chance and give it some allowances due to what is obviously a low budget. But it is literally not even half the movie the first one is.
Characters do things that don't make sense, the dialogue is often unnatural, and scenes that should be suspenseful just aren't. Not only that, but I at least expected the baddie to be one or more giant sharks, but for most of the movie that isn't the case. Instead it's baby sharks terrorizing people piranha-style, which just didn't work for me.
The only improvement upon the original are the effects. The first film has some REALLY weak CGI and I think the sharks in this one, for the most part, look better.
With all that said, if you're someone who tends to enjoy cheap B-movies even when they're not actually very good, then maybe it will still be worth a watch for you. Maybe. But it literally almost put me to sleep.
