All comic book adaptions.
Black Jack SP - Story about the character's beginning. Compared to stuff like the anime series, it was pretty awful.
Because it was a beginnings story, Young Black Jack's character just didn't have the charm of Black Jack in his older form (which is what we're used to seeing).
Saijou no Meiji - Basic hospital battle with main character wanting to save every patient he meets, against his evil enterprise overlord boss. Not bad, but nothing surprising either.
Another Gantz - Didn't read the comic, or see the 1st movie.
My guess. Made-up character narrating what happened in the 1st movie, so people could watch this instead on tv, and then go watch Perfect Answer.
I think the characters didn't develop enough since the SP focused so much on the action. Just felt it needed more emotional moments for us to attach to them. Which is a shame, cos Nino and MatsuKen can both do great emotional scenes.
Other than that, it's pretty good sci-fi.
