Well, I'm a little late in posting, but I saw this movie on October 20th when it aired up in Brisbane as part of the Japan Film Festival.
I'm glad I was spoiled on all the plot important details beforehand, because my expectations were set low enough that I was able to come away without being disappointed. It would have sucked going all the way to Brisbane to see it without being ready for that.
Anyway, the movie hadn't changed my opinion on anything I thought going into it. I still didn't like the Godly ki, or Super Saiyan God, etc. The only thing this movie had for me was the gags and character interactions, which were enjoyable (and also, the thing I hadn't been completely spoiled on). Even knowing some of Beers' quirks before-hand, his personality still surprised me, and I think he was given an excellent personality without being
too quirky. Even Whis was enjoyable despite not doing much. The moment Kaio and Goku drove around his dinky little planet had the audience laughing harder than any other scene or gag in the movie.
I feel the movie really lost a lot of it's humour once it got to Bulma's birthday party, but some of the moments were still funny. Once the fighting started, and the plot took centre stage, I was completely uninterested. It didn't help that I had already seen everyone vs Beers to know it was going to be bland before hand. And even as a big fan of Vegeta, his spotlight just really left a bad taste in my mouth.
The Goku and Beers battle... just really sucked, to me. From the start to the very finish, it was the lowest point of the movie for me. I was glad once it was over, and that the movie had some more interactions after that (Goku's teasting of Vegeta was funny). The credits were really cool.
Also, I don't know if anyone else who saw this in theatres got this, but at my theatre there was a message from Masakazu Morita (Whis' VA) before the film started. I didn't even know he was voicing Whis at that point, so I was pretty damn surprised to find that out right before the movie.
Definitely agree that this didn't feel like a movie. Just felt like a very long special... one that refused to end once the fighting started.
Overall, my opinion of the film hasn't changed much, if at all. But at least I was able to enjoy the bits that I enjoyed out of it, rather than nothing. I'm not sure if I can watch this again once (well, if) it gets dubbed by FUNi, though.
