Right-io. So I found this movie pirating website that actually has the FULL MOVIE for watching available in VHS quality at the below link. It was videotaped at a screening in China, but they did a pretty good job.

I know its scheduled to be state-side on April 8th, but hey! Why waste an hour of your time in theaters when you can watch it for free, right?
Yes, I did say an hour. The movie is roughly 70 minutes long and so full of cheese, it almost made me blush. While its neat to see a real-life, strapping 18 year old Goku kamehameha a few times and fight alongside Chow Yun Fat, its really...quite disappointing. Maybe if I were 5 again it'd be worth it, as I was constantly reminded of the first Power Rangers movie and how awesome it was back then... Yet even still, this movie didn't hold a candle to Power Rangers. I dare say that it sucked worse than most made-for-TV movies I've seen in the last decade.
Be your own judge, though! Let me know your opinions, too. If you were ever a fan of the series, I know you're gonna watch it. Sorry to disappoint though, dudes.
