So, might as well chip in with my opinion now I've thought about it...
It was decent enough, but the pacing seemed really weird somehow, not sure I can put my finger on what exactly it was about it.
The character stuff was nice and the action was very well-choreographed, especially compared to a lot of DBZ anime stuff...I
think it was pretty funny, but my spoken Spanish isn't great so I didn't catch too much; I'll rewatch it when Funi gets through with dubbing it or something so I can fully understand (or if Toei/Funi releases a subbed DVD over here).
I did have a few other problems:
1. Clearly pressed for time and/or basically just treading water until Super, due to--as many people have said--declining to go into Frieza's training, and SSGSS at that.
2.
3. (Minor point, this one) I dunno about the designs. I actually think SSGSS looks pretty cool objectively, but it's much less interesting than what it's replacing (SSJG). And I kinda liked Frieza's new form at first in promotional material, but I didn't really like it actually seeing it in the movie. Then again, Dragon Ball is full of off-the-wall designs and looks, not every one of them has to ooze badassery (I didn't particularly like the look of Semi-Perfect Cell but it didn't exactly kill the Cell Saga or anything so melodramatic).
So overall, I liked BoG a lot more than this, but I think a lot of the issues with RF won't be, well, an issue with Super's series format giving them more room to breathe. (And overall, this was fine, it's hardly terrible or anything. It was sort of on par with some of the Toei movies, but with a bit more character than any of them.)
