I said it the other day but out of the mainline X-Men movies DOFP is second only to First Class for me (X2 is a not too distant third place). It's got some great moments and it acts as a worthy finale to the original movies and a solid follow up to First Class.
Now this I can't really argue with. Of the mainline X-Men movies not counting any of the spinoffs, the only one that really stands out to me as far as action sequences is X2 and the opening Nightcrawler White House scene is a big reason for that. The other movies had some interesting sequences here and there, but it was usually few and far between like the fight choreography in the first movie, the Golden Gate bridge scene in The Last Stand, Magneto lifting the sub in First Class and the "Time in a Bottle" scene in DOFP if that counts. When it comes to action in the overall franchise, both Deadpool movies and The Wolverine stand out a lot more.
