The Mighty Morphin Power Rangers movie is set as an alternative story as to how the rangers receive their ninjetti powers at the start of season 3; if you watch the series you'll find they receive their ninja powers in a different manner. This doesn't mean, though, that if you've watched the series you shouldn't watch this, far from it! As other reviewers have said it's Rocky, Aisha and Adam in the movie, not Jason, Trini and Zack, but that's the same as in the latter half of Season 2 that I think was airing at the time they were filming the movie.
The Turbo movie is okay, maybe not quite as good as the first power rangers' movie, but there is a fairly decent plot to this one too. In this one you'll find the same actors from Power Rangers Zeo in it, but Steve Cardenas who played Rocky decided to bow out at this point, and is replaced by a young boy called Justin, who is a touch on the annoying side, simply as he is a lot younger than the other rangers.
All in all I'd recommend this to old and new power ranger fans alike! If you have children and they are more familiar with the later seasons like Operation Overdrive, Jungle Fury and RPM, I recommend they watch the original power rangers to see how the legacy began, as they really are worth a watch! And hopefully they'll watch them over and over again, and it'll keep them entertained for a while!
Or if you're an old power rangers fan, who has these on video - upgrade to DVD, you have nothing to lose, and a lot to gain!
