Yeah if you watched the original it was slow paced at the start, and then later on shit hit the fan... literally in a few episodes stuff got crazy. I'm expecting the same from this... remake? of the original as they start going into...
Spoiler: show
The anime is listed for 25 episodes, so I pretty much expected them to spend time to build the group/background story of all the characters and get you familiar with everyone sort of speaking, the action should be coming up in a few episodes. The best stories at times are the ones that make you really feel for the characters after all just before it gets really dark
