If you haven't yet seen Martian Invasion, you are missing the blockbuster of the summer! This action-packed film has the best special effects I've ever seen. It also has a believable, suspenseful plot, which is rare in the sci-fi genre lately. The movie stars Blake Ebers, whom you may recognize from last year's Across the Desert. Leading a solid cast, he puts forth a great performance as the main character fighting the alien attack. Do yourself a favor and see Martian Invasion today. It's even better than the book.
