The jump in video quality from the first Open Water movie to this one is astounding. But it's still real bad. Plus, this isn't even a shark movie! I know it isn't specifically touted to be one, but I was still very surprised. Honestly, I think what happened here was someone wanted to make a very stupid movie, but were then informed that a movie, near identical in both plot and stupidity, already existed, and to cover their tracks, they quickly decide all of a sudden that this movie was a "sequel" to the original Open Water. I guess it was kind of cool seeing the guy that plays Loki/Gabriel in Supernatural in another role, but I can't imagine that's a thing that'll carry much weight with audiences in general.
Final rating:★½: - Boring/disappointing. Avoid where possible.
