Yep, I can surely say that this serie is one of the best I have ever seen. Now, for the other fans that probably thing I'm not an otaku, well, I have also watched the next season (Eat-Man 98) and I still prefer the older one... even though the creator had nothing to do with this one, it pretty much doesn't matter. The main reason I prefer the old serie is that Bolt-Crank model looks like a cold youngster in the 98 season, meanwhile on this one (97) he looks like a cool, awesome dude with nerves of steal.
It's a miracle that such a great serie was made with such little budget... unfortunantly, the quality is really poor, as the same with the length of the serie itself (just 8 episodes), but the awesome dialogues and the original idea of creating one mini-novel for each episode really catch you up, wanting to watch each episode.
I give it a A. With all its drawbacks, considering the low budget it's really a master piece. Watch it, you won't regret it.
