X-Men: Days of Future Past is a disappointing entry in a film series that now stretches back 14 years and almost half as many movies. It's disappointing mostly as a matter of pedigree; had Days of Future Past been made right after, say X-Men 3: The Last Stand, or the regrettable X-Men Origins: Wolverine, Days would seem like a genuine improvement. As it stands, though, the movie suffers from its placement after 20th Century Fox's two most recent X-Men knockouts—the surprisingly adroit X-Men: First Class in 2011, and 2013's (and this reviewer's favorite X-Men iteration) The Wolverine.
The greatest irony of Days is that it wouldn't seem half so bad if it weren't for the presence of movies like The Wolverine, which make explicit the problems that are implicit in movies like Days and The Amazing Spider-Man 2.
