I thought it was average really (Battle at Big Rock that is); the scenes were pretty much repeats of what we'd already seen with the JP sequel, and it didn't really add to what was going on, other than showing a camping ground with dinosaurs (we had that in TLW too). Two arrows to the head of an Allosaurus wouldn't have been nearly enough to scare it off either, not if it was hungry which it obviously was.
I also know it's only fictional, but (in the real world) if there's a dangerous shark, or dangerous bear roaming around, it's hunted and captured, or killed. Here we're suppose to disband belief and accept that no agency or government body has decided to contain these creatures? There's not many of them left as it is if I recall correctly anyway.
I'm genuinely curious to see how they're going to do the third JW instalment. There's only a handful of Dinosaurs left, unless there's another island somewhere that we've all forgotten about (even though there are actually already two of them and JW seems to focus only on one).
