This was a thrilling sci-fi good time, with a huge budget and some great action sequences. It does, however, suffer minorly from somewhat of a poor script and subpar acting. And while the aliens look cool in their "Halo" styled spacesuits, their humanoid appearence behind their masks is, admittedly, rather laughable. My preferred alien look? Pale, soulless white eyes, fangs, and an ear piercing screech. Anything else and you're just using an old formula that was never good in the first place.
But I am still giving this four stars because the action sequences succeed, however silly and over-the-top they may be. And the part where they use a 1942 steam-powered battleship with a crew of WWII vets to beat the aliens was a fun twist that brings similarity to the boardgame. Totally recommended for anyone looking for good means of escapism.
