Re: What was wrong with the current trilogy?
the biggest problem with this franchise that a lot of the characters were "water" down. The only characters to have development overall were Wolverine, Magneto and Prof. X. the others were just there, or may gotten a little story (Rogue, Bobby,Jean).
The movies never shown the X-Men as a family, nor the team interact w/one another, we never saw a Jean/Rogue, Scott/Rogue, or Storm with anyone, etc some of the best character interaction scenes were in X1. One of the reasons the Avengers were worked so well because that team dynamic was present, it showed them argue, crack jokes, struggle/bond to become a team. The X-men didn't have that chemistry, and I partially think turning a few of the characters into "teens" didn't work when you have several "older" X-Men. It felt the older X-Men were handling business while the teens were tangled in "high school" drama.
The X-men world is huge! So many villians, so many mutants, it should have been cameo haven! I'd love to see a F.O.H protest, Anti-Mutant posters w/Craydon Creed pictured on them,a morlock running into the sewers. It's these little things that make movie have more depth, awareness and give a nod to the fans.
