Based solely on single player. It took me less than an hour to beat it on the default difficulty, then I beat it with all 6 rangers, sticking with the same ranger for every fight.
I'm not a big fighting game fan, so I don't have a whole lot to compare this to, but this just seems like one of the lower quality ones out there. The hit boxes are horrible. I would slash through the entire enemy sprite and not hit it, while getting hit when I was quite a ways away from the enemy's weapon. I guess once a move is initiated, that character cannot be hit. But not always. Being in midair seems to be a pretty safe spot.
The game is extremely short, as evidenced by my beating it in less than an hour when I'd never played it before, with only 5 stages (the manual scan I found online says there's 7 stages), each with two different battles -- one as a ranger, one as a zord. Each battle is a single round, as opposed to the best of 3 that's standard from the small number of fighting games I've played. Basically you fight one of Rita Repulsa's baddies, and after defeating it, it grows to where you need to fight it as a zord. You get infinite continues.
It is a kinda nice change in that you don't pick one ranger to play through the entire game, but rather choose any of the 5 or 6 at your disposal for each battle. After defeating the brainwashed Green Ranger in the 2nd stage, you can use him from then on. If you use him, you'll use the Dragonzord for the zord battle, rather than the Megazord you get for the other 5 rangers. Each character only has 3 or 4 special moves, so it's easy to memorize all the moves, although it does get a bit monotonous. While I don't like the crazy amount of moves in things like Mortal Kombat, this is just too few.
I never watched the show (beyond part of an episode or two to see what all the hullabaloo was about), so there was no "cool" factor for me of being able to fight as rangers or zords, which I'm guessing was a big draw for this game.
