In the last few weeks we've had three almost completely pointless short trailers online, with another reportedly playing in cinemas ahead of Avatar: Fire and Ash. First there was Captain America cradling his baby, then Thor praying to his dear old dead omnipotent dad. This week we got our first proper look at the classic X-Men lineup in the new film, and there are suggestions that an encounter between the Fantastic Four's The Thing and half of Wakanda is imminent. Something weird is clearly happening.
