The Good: dinosaurs and Japanese Zeros in air-to-air combat! The Bad: SyFy Channel 'zero budget movie-of-the-week'. The Ugly: Bad writing even for SyFy Channel, supporting cast.
The concept is great for an afternoon popcorn flick, and the storyline *in general* didn't require too much suspension of disbelief (no impossible physics, or blatant violations of common-sense science that seem all-too-common in recent movies). However, steps taken to get from plot-point A to plot-point B often made no sense at all. It's as if the script were outlined by a decent writer, then fleshed-out by a 12 year-old.
It's no mega-budget blockbuster, but the effects were actually very good for the budget level. *Everything* was done using cgi and green screens though, including anything with a plane in the shot. The picture is good enough, but the not-quite-right flight physics make the effects rather noticeable (look away from any landings, trust me). It works well for the creatures, not so much for airplanes. 10 minutes of stock footage of WWII planes in flight would have made this film much more enjoyable to watch.
The male and female leads do a good job with what they were given, which wasn't much (some of the dialog was just painful to sit through). Some of the supporting cast, however, made me cringe whenever they had speaking parts. In their defense, they were trying to overcome a script that was even worse than the usual SyFy weekly offering.
Overall, the effects were good for the budget, but not enough to make up for the poor writing or mediocre acting. A tolerable 'fix' for those who crave sci-fi, but a disappointing take on an interesting premise.
