Giant, man eating, super intelligent sharks make life miserable for a group of researchers.
Deep Blue Sea
Sometimes you want to just sit back and be entertained. Deep Blue Sea is the perfect movie for that. Director Renny Harlin has a track record for making very entertaining over the top action films.
While the movie does take some silly turns here and there, the action moves so fast that you don't really think about it until after it's over. With some very impressive animatronic sharks chasing the actors around, the visuals are often astounding. Occasionally some bad CGI creeps in but it never detracts from the overall enjoyment of the film.
