I'm not trying to start an argument, but if you like to laugh at bad movies (as I do), you just might find this movie to be very enjoyable.
Maybe I've just got the wrong attitude for the Internet, but I can't bring myself to get upset when someone disagrees with me about a movie.

That said, it's important to know where I'm coming from. I love laughing at "so bad they're good" movies. I own Jason X, Dracula 2000, and Deep Rising on DVD, among many others.
And I still thought MSvGO was so bad it wasn't even laughable, it was just painful. There are a few "good to laugh at moments" (and yes, the shark scene you mention was one), but overall, I felt they accounted for less than 10 minutes of an hour-and-a-half movie. Not nearly enough to make up for the agony of the rest of it.
