Yeah, X-Men 1& 2, First Class, and Days of Future Past were really good. All those had former indie directors who helmed or produced smart crime/action thrillers. Bryan Singer (XM 1&2, Days OFP) had directed The Usual Suspects. And Matthew Vaughn (XM First Class) had produced Guy Ritchie films, then directed Layer Cake and Kick-Ass, then later Kingsmen.
And the Dark Knight trilogy stands apart as a landmark in comics movies. Writing/directing that had smart action, and drama geared to adults, not just an adolescent audience.
