The second is better. I especially enjoyed the large number of references to other mutants that couldn't possibly all fit into one movie.

I'm still skeptical of the Superman and Wonder Woman movies. Wasn't J-Lo signed on for the latter at some point?

Oh, and has anyone else heard that the next Spiderman will feature Venom, as played by...wait for it...Topher Grace. I have no idea how that could work at any level whatsoever.
