The one thing that really bothered me...
Other than the death of a dog being used purely to illicit an unnecessary emotional response...
The island they were on. It was mentioned it was a tidal island. However, despite it being a tidal island, there would have been plenty of room for them to have waited there til the morning. The block of trees seemed wide enough, especially considering with tidal islands the water doesn't go straight up to the foliage line and leaves several feet available, otherwise the plants would be drowned.
Not to mention that when you shine lights on crocs in the night they freeze. They don't move. But that's me being a zoologist and over-analytical.
Otherwise it was a good creature feature.
I still believe that peace and plenty and happiness can be worked out some way. I am a fool.
