(Warning, minor spoilers) I have watched many shark films, my favourite being Deep Blue Sea, and a lot out there are quite boring, but this had a unique great storyline and the acting was great, it showed how humans react to being in danger, and selfishness, the scene where they are trying to go out of the hole and the one girl is getting out but the other gets scared and grabs onto her making the rope fall was just perfect. I didn't bother to watch the first one, it got boring after a little while, but this one kept me interested. A few minor plot holes being my reason for only 4 stars, but overall it was pretty good.
