The plot is pretty much what you have seen before. A group of people with special abilities who are good fight against a group of people with special abilities who are bad for reasons X, Y and Z.
Having said that there are some interesting little plot twists that keep you interested and there are soem very funny moments throughout so you won't get bored.
The characters are OK although three out of the four main characters really annoy me (the exception being Eve). This is however, made up for by the secondary characters all of which I think are great.
Tha animation is solid but not great and they do take a few shortcuts. The voice talent is also pretty good and considering some of the shockingly poor dialogue that is impressive.
All in all this is a show with good elements and bad elements, but it is still pretty good and wortha watch if you get a minute.
