I think we might have gathered a few too many X-Men, you guys.
Not that I mind a whole lot of X-Men. It just makes for a very scattered theatrical trailer, where it feels like all of the things are happening at once. Maybe Bryan Singer is making them cut the X-Men: Days of Future Past trailers like this on purpose, to symbolise the dangers of temporal anomalies.
If you ask me, this is way too much work. Just play some music, show a picture of Blink, and toss “Whole Lot Of X-Men, May 23” over it in big letters. Movie ticket sold.
