As a die-hard fan of the films and comic books I thought I'd give this a go despite the previous review, and you know, it really wasn't so bad. There is a single story thread, which I liked (comic fans will see some very strong similarities with an existing story, transposed to Japan). The art work is mostly attractive, and yes, the females are over-endowed (can't imagine Storm walking upright let alone getting off the ground) but are they really as outrageous as some of the art work in the comics (thinking New X-men here)?
The team is Cyclops, Woverine, Storm and Beast (the latter two rather underused in favour of star appearances by Armor - often annoying - and Emma Frost). The action is not that non-stop. If anything, it can be a little slow. The number of times I wanted to kick someone into action before they got trounced...but no; they just got trounced. And the team doesn't work as a team. One guy goes up against the bad guy, gets trounced, the next guy has a go...you get the picture. The team thing is the reason these guys are supposed to win. But hey.
So it isn't non-stop action, no. There is a quite a lot of sitting around emoting. Cyke is at his angstiest, Logan is pretty growly, even for Logan, and Emma is way, way too nice. Creepy.
Is it as grown up as it claims? Well maybe a little more than the 90s series, and way more than Evolution, but it isn't grown-up grown-up. It's just on the dark side.
The extras are really nice. My main gripe is that the DVDs play badly on one of my multi-region players, skipping a whole lot, and won't play at all on the other. Maybe it's fine on a region 1 player. I'd have maybe gone to 4* otherwise.
Overall, though, glad I bought it.
