I bought Starship Troopers III and watched it the other night. It was far better than the second movie, which was seriously bad, and more like the first movie. However, it lacked the satirical edge, and was played straight, and grim. Jolene Blalock was in it, along with her usual one-note acting. At the end of the movie, the Mobile Infantry appears as Heinlein had it in his novel, so many years ago.
If you hated ST II, go see this.
