Ah good to see the usual crowd are out to instantly write off an entire film from an under 2 minute teaser because, ya know, women. But sure lets compare the Marvels teaser trailer against a full trailer for, arguably, the best film in the MCU. Not to mentioned the wholly different tone and subject matter of the films; you might as well try to compare a Superman film to Bridge of spies.
Anyway, the trailer looks OK. Pretty generic MCU and doesn't look like it'll be the best film but equally not worth MCU film either. The switching places could make it interesting but could get old very fast if they over do it. Probably not a film to go the cinema for, but none them after End game have, but one to watch on D+.
