DBZ haters are cutting their wrists somewhere!
I want to mention some things I liked so much about the movie,
Regarding the movie:
The character development and interaction is AMAZING. Vegeta´s dance scene was funny yes, but the movie really makes you feel that he freaking lost his pride for the sake of the earth!. he himself states this, after Goku finds out he says his respect for Vegeta has only improved because of that, Vegeta protecting Bulma was the final touch to Vegeta´s humanitation before the last episode of Z

.
Goku gets a new insight as he is revealed to be PROUD just like any other Saiyan, as he feels insulted by the fact he needs other´s power to atleast evenly fight a foe. This also tells us why he only uses the spirit bomb as last resort since he needs the power of other people, also tells us that Goku was disgusted at the idea when doing it, just that he didn´t voice it out!.
He also gets a lesson of being Humble by none other than Bills, and by giving up to him he seals the Master/student relationship he has started with Bills. which is immensely emotional.
Bills as a character is amazing, He at first glance is a fearsome villain who freaks out over anything and destroys anything that tickles him, meaning his behavior would be like that of a greek god or some o that. He also has his tender moments like Lecturing Goku when they fight and by lying that he didn´t have enough energy to destroy the earth (he was clearly unscathed). And let´s be honest, his work is to destroy Planets, Galaxies, Solar Systems, every other deity in the 7th universe fears him. of course he wouldn´t even doubt destroying a planet like earth without getting attached to it (like he did with Goku) after, his work can be compared as if you were hired to flame ant nests around the town!. His behavior is perfec to his position!. He also mantains a professional behavior when around others but goes childish when he´s only accompanied by Wiss!.
When Videl reveals she´s pregnant.... amazing momment!. acompanied by great music! nuff said!
There´s much more but that will do for now!
About the Mexican dub:
Goku´s dialogs are simple. as his japanese counterpart is supposed to sound, a nice touch was that after King Kai hit him because of his "arrogance" talk to Bills, he started to forcefully trying to use elegant terms to talk to him, this of course was completely left when he got pissed at him fighting underground. That was a good touch!.
Bill's Voice actor makes him sound a lot like the japanese one! you get that feline sound when he speaks! really gives him more insight as a character.
Also when they finally make goku the super saiyan god, when Gohan brings Videl she tells him "But he/she´s not born yet my love" and that was sweet! by the way in out langue there was no indication wether the baby was boy or girl but I had to translate it to english so had to use he/she!

(we know it´s a girl though lol)
There's room for only one snake, and one big boss.
