No. Some of the x-films were good, especially at the time they came out, but even those haven't aged all that well. And let's not even talk about the FF.
That is not to say that i don't have concerns with how the x-men will be incorporated into the mcu, as i feel like they work best in there own universe... otoh with Cap and Iron man gone there is a void that the FF or X-men could fill, potentially.
EDIT: I forgot about Daredevil, and elektra. probably for the best.
