It's not even like X-Men is total garbage, either. You can have some fun slamming the ragdoll soldiers around, watching them crumble and collapse over fences and computer terminals, but after the thousandth guy bites it, you'll be ready to move along.
If you're so inclined, you can collect hidden tokens in each level to unlock training missions and secret costumes, though spending more than the absolute minimum time required in each level is not recommended. This is a frustrating, derivative movie tie-in that will likely bore even the biggest fans.
