Turbo: A Power Rangers Movie is more or less the same quality of entertainment as the first movie and the various television series with over-the-top performances and a thin plot, though I guess if you’re a fan, you might find it to be fun.
Mighty Morphin Power Rangers probably was in line with the television series with a bigger budget and I suppose if you’re a fan of that style of adventure and comedy, this might be worth watching, though it is dated.
Ninja Turtles: The Next Mutation” is just a bad series that I suppose young kids might enjoy but any fan of the original will find to be an abomination that will lead one to appreciate the newest incarnation.
This “Power Rangers” Seasons 13-17 set is another solid seasons of the long-running, enduring series. Sure, its cheesy as all hell, the acting isn’t the best but it’s also entertaining in the breezy sort of way. This season set compiled by Shout Factory offers up OK audio/video transfers and some well made, newly recorded featurettes.
“Power Rangers”: Seasons 8-12 is yet another great set from Shout Factory with satisfactory audio and video transfers and, as far as I know, all the features captured on one disc. Now, it is quite expensive (it will be around $75 when released), so you really need to be a hardcore “PR” fan but to me, it’s worth it.
