The film is long, generic and absolutely uninteresting.

I mean, a group of mostly inexperienced people decided to delve into a random cave and also bring a pregnant woman with them. You can't write characters that are more stupid that these, really.

It was mostly fine on a technical level, but there's just nothing interesting about the characters or the story, no interesting locations, visuals, anything.

I understand that maybe the creators wanted to make it look realistic and dry, but you have to have something in your film that will capture the viewer's attention, just having stupid people in it doesn't help, nor does help having a love triangle subplot in a crisis situation. And yeah, the ending is just ridiculously bad.

As I scanned through the reviews it become clear that this is a sequel to a popular film I haven't seen (which is much better), so I'll guess I'll check it out as well.

Surprisingly enough, this was a very weak attempt at a croc film provided that Australians have some really good films in the sub-genre, like Rogue (2007).

This is very skippable. There's absolutely nothing in this that will horrify or entertain you in any way.
