I thought it was ok but not great. Really could have used a lot more on the ground fights. I think it says something that a big budget movie couldn't live up to a 90s kids show with people in spandex fighting.
As for the characters they did a good job with Jason, Kimberley and Billy but Zack and Trini may as well have just not been in it. They really need to get more focus in a sequel.
Zones looked crap, not much else I need to say about that.
