For these big budget films recently they seem to have gotten the definitions mixed up. A teaser trailer is usually meant to be under a minute and more often than not doesn't reveal much about the film's story (most of the time not even having a whole lot of actual footage), whereas this easily qualifies as a full length trailer. Perhaps this has something to do with the irritating phenomenon of so many recent full length trailers presenting the audience with 90% of the film's plot, which no trailer should ever do. Really, even a full length trailer shouldn't reveal any more than what was shown in this 'teaser'.
Anyway, I didn't like either of the first films, but I'll probably end up seeing this anyway.
