People who are sticklers for historical accuracy should probably avoid this one, but I found it to be a very enjoyable, fun movie. Flyboys is about the aerial battles of a volunteer American group flying for the French in WWI. General advice to enjoy this movie is to expect nothing. Formulaic plot (what movie isn't, nowadays) but the dogfights between the wooden bi-planes are nicely done. The zepplin scene is probably the best action sequence.
Also watched The Guardian and Gridiron Gang. The Guardian was watchable, as long as you're able to endure Ashton Kutcher. His annoying grin isn't full-blown in this movie, so that was a plus. Gridiron Gang is another Hollywood inspirational youth sports movie and a decent enough football flick.
