With X-Men: Days of Future Past dropping this weekend, the Cinema Excelsior crew invites you to journey all the way back to 2003, when this franchise made the leap from good-time popcorn fluff to thoughtful, sophisticated entertainment (but before the - ahem - unpleasant business that followed). X2 is a seminal installment in not only this series, but in the comic movie canon. Does it hold up more than a decade after its release? SPOILER: Yes, but what's most interesting is why.
