"Attack on Titan: Part 2" might be an improvement over its predecessor, but it's better in the same way that "Star Wars: Episode II- Attack of the Clones" is better than "Star Wars: Episode 1- The Phantom Menace", which is a bit of a backhanded compliment.
"Attack on Titan: Part 1" won't likely satisfy anyone, as it's a weak adaptation, a weak standalone film and doesn't excel in the action or horror departments. But it's not unwatchable either and can even be enjoyable with the right crowd.
"Dragonball Z: Resurrection F" was f@cking awesome, although I have to admit that part of me suspects I'm critiquing the experience more than the actual movie. I saw this in theaters with an energetic crowd and their enthusiasm was contagious.
"Black Lion" seems to have been intended to be a pilot for some sort of series, as it doesn't explain anything, but the ending promises that all will be revealed in 'time'...except that 'in time' never happened. Yet the only reason anyone should be watching this is for the gore and unintentional hilarity- and "Black Lion" gives us lots of both.
I don't know how closely "Kamui" followed its source material, but somehow there is so much story that it ends up feeling like there was no story at all. This isn't a bad flick and I will concede that there were some cool moments, but "Kamui" tries too hard to be something it's not- a manga. Wong medium, guys.
"Dragonball Z: Wrath of the Dragon" is... different, and not in the way that "Fusion Reborn" was different- where it felt like the filmmakers were subtly adapting a 'Goku x Vegeta' slash fanfiction while tripping out on drugs. This one just has different priorities, toning down fighting for the sake of fleshing out and developing its primary character.
