Saw it the other weekend
A decent DB movie.
Not an amazing movie, but full of nostalgia in my case.
A piece of advice for anyone wondering whether to see it, I would recommend watching the new anime season, since it will make a bit more sense and background to what is shown in the movie, otherwise if you come from DBZ you might be a bit lost.
(Also, note that DB: GT it's not canon anymore, even though it was epic, for me Baby and SSj4 was the coolest thing)
Overall it's a cool movie if you are into DB and you feel a bit nostalgic. If not, there is no point in going.
