I'm not a Jean-Claude Van Damme fan, but I walked in right as The Younger Son started this film so stayed to watch. Legionnaire is a 1998 film with a plot hole so large you could drive a truck through it. That initial problem is compounded by being followed by other events equally illogical in this story's universe. This film is now #1 on my list of movies with plot holes so huge they are made ridiculous or unwatchable by them, and there's nothing here that can overcome this fault. I spent the rest of the film saying, "but... but... but...".
Oh, ok, so maybe I'm willing to admit that the plot hole in Moon is bigger. Maybe.
Rotten Tomatoes gives it a score of 29%. EW says, "...Schwarzenegger he ain't. C-".
