I flicked to the SyFy channel near the start of the movie and instantly judged this to be a cliched, awful CGI, straight-to-video B-movie, and while it is these things, it is also surprisingly watcheable.
After marooning on a desert island, the cast find they are not the first to be marooned there, in addition there are also dinosaurs, well it is the bermuda triangle.
The CGI is very outdated and you have to force yourself to believe it for it to work. The female and male roles are very cliched with women being supportive and men being action-oriented, they are generally ridiculously brazen and immune to post-dino PTSD. Having said that couples are given more than a few moments of embracing and it definitely seems that no-one is an island on this island. These heroes are human.
I was surprised to find themes of brain over brawn, with solutions to predicaments typically having a plan created, and with the final plan being thought up out of geeky scientific knowledge. I was also surprised at the level of working together and the lack of animosity, especially when the nazis are encountered, as it turns out to be more like that Christmas football game in no-man's land than trench-warfare. There is some skullduggery, but overall the theme is of helping each other, and teamwork!
The movie ending is fairly warm-hearted and positive.
