I've had a pretty lucky run so far and at no point do things get luckier than managing to see the new Broly movie before it even comes out in this country, but why stop there lets add the others as well.

Battle of Gods
Taking things in a different direction to GT, this movie begins with Beerus, a Destruction God intrigued by a dream he had of fighting a legendary Saiyan warrior. His caretaker Whis informs him that there are still Saiyans left despite their apparent exitinction at the hands of Frieza.
This takes him to Earth where he crashes Bulma's birthday party, but with only Vegeta even recognizing who Beerus is, he swallows his pride and tries to get the others to act as sensibly as possible with mixed results although Beerus does enjoy the food he quickly stops being friendly when he argues with Majin Buu. Goku shows up having already been beaten by Beerus on King Kai's planet to have another shot by obtaining a new form but despite his best efforts he still fails to beat Beerus but he takes pity on the planet because Earth has the best food.

Resurrection F
After many decades members of Frieza's army manage to wish the tyrant back to life with mixed results again which hilariously starts out in pieces as he's not been put back together following his death at Trunks hands.
After being repaired Frieza realizes if he stands any chance against Goku he has to actually train which works as he comes back in Golden form and fights both Goku and Vegeta sporting their own new forms which results in Frieza losing again. The difference is he destroys Earth which forces Goku to admit his own faults but Whis gives him a second chance which allows Goku to finish the job.

Broly
The first part shows an alternate version of the final days of the saiyan race painting Bardock in a much more sympathetic tone as he personally sends Goku to Earth. As for Broly, fearing his power maybe too much even for the Saiyans, Broly is exiled with Paragus searching for him.
After many decades Broly is found by Cheelai and Lemo hoping to win some money from Frieza's army. Frieza hoping to take advantage of finding two Saiyans to use against Goku and Vegeta jumps at the chance of recruiting them. What follows is the longest uninterrupted fight in Dragonball history as in this order fighting Broly is Vegeta, Goku, Frieza, Whis and then Gogeta.

All three follow the same formula, one big battle but unlike the Yu-Gi-Oh films which pretty much do the same thing there's a point to them.
They all serve as extended trailers to the Super Anime with Broly being the greenlight for season 2 and if the ending is to be believed we haven't seen the last of Broly.
Dub is always top notch and despite Broly's origins, the Super does portray Broly as more sympathetic which is miles better than Z's, because Goku wouldn't shut up reason.
Final Verdicts
Beerus film, welcomes fun new characters badly needed in the franchise and the overall presentation is impressive but still painted with Toriyama's terrible brand of Comedy.
Gold Freiza film, I feel is a let down considering were dealing with one of the franchises most notorious villains.
Broly film, holy hell is it impressive to watch and the changes to the backstory really improve the story as a whole and I welcome this Broly over that other Broly.
