I still don't care for the Doom origin there, I don't understand what Galactus is doing, and the ending appears a bit anti-climactic. But, I haven't read the full leaked script. Maybe pacing, acting, and good direction could make all of that work. But certainly, injecting some straight-ahead action into the movie, and taking itself less seriously would probably be beneficial (this coming from a guy who hasn't seen the Trank one, and probably won't for a very long time).
