Singer directed days of future past, which was excellent.
I wasn't sure if he did that one or not, but I thought it was weaker than the previous 1/2-boot.
It was OK, but reminded me of why I thought something like X-Men would always be difficult for a movie--so many weird stories involving space, time travel, psychic realms, alien bugs and spirits that an "honest to the comics" X-Men story would just be way too bizarre and involve way too many undeveloped characters to make any sense on the screen.
I thought DoFP had some really cool moments and actually did as well as it could by pushing those type of elements onto the screen, but it still felt like a big old mess to me.
That's what I liked about how Singer initially set up the movie versions--focus on a single character that is probably the less-strange of the bunch, and whose central story is often considered to be lifted direct from a semi-obscure thriller series that came about ~the same time as Wolverine (the Bourne stuff)...so audiences could appreciate that.
(actually, did the Weapon X storyline come long after Wolverine's actual origin--which was 1974 or so--meaning that the Bourne stories would have been around long before that was dropped into Wolverine's origin?...anyway I digress)
