One of the only reasons I watched MM! (in fact, the only reason) was because I thought one of the characters, Mio Isurugi, was cute and unique. I liked her so much that she even made it to 3rd place on my list of top 10 girls of 2010. Your first impression of her from the first few minutes of the series is that she’s just going to be another petite, short-tempered tsundere, but Mio takes the “tsun” of “tsundere” to the extreme. Rather than lash out with verbal abuse and a few punches, Mio takes pleasure from beating and torturing the main character, Tarou, to near-death. Add to that the fact that Tarou is an extreme masochist and you have a comical relationship unfold.
Besides the sadistic Mio and masochistic Tarou, there’s also an androphobe, a cross-dresser, a loli scientist, a lolicon, a lesbian, an otaku, a cosplay fanatic, an incestuous sister, and an incestuous mother. MM! basically brings all of the major fetishes that you can think of and stuffs them into a single show. With all of this material to work with, you’d think that the anime would turn out to be rather interesting, but it’s actually far from that. While the silliness of the anime was enjoyable at first, it started to get old after a few episodes, and without any sort of real plot development there isn’t much to keep the average viewer going. The story moves from trying to fix Tarou’s masochistic tendencies to trying to fix everyone else’s problems and somewhere along the line it just felt like the writers forgot what the anime was originally about, ending off with Tarou having somewhat of a harem + 1 cross-dresser.
Although all of the characters have some quirky thing about them, most of them lack any depth and are portrayed with a one-track mind. Mio and Arashiko (the androphobe) were the only exceptions to this, but even then it was obvious that their backstories were hastily slapped together. If someone were really suffering from traumatic experiences in the past, it would take more than a few kind actions to make them better.
The anime wasn’t a complete waste though, as there were two scenes (yes, out of 12 x 24 min) that I really enjoyed. The first one was in episode 5 when Tarou had to use his “hentai powers” to destroy a machine that was turning everyone into perverts. I got a good laugh when he turned into a super saiyan ^.^
The second scene that I enjoyed really had nothing to do with the anime, but had a lot to do with the production company, Xebec. As some of you long-time anime watchers may remember, Xebec created the most awesome anime ever, Martian Successor Nadesico. They also created the most awesome anime character ever, Ruri Hoshino. Sadly, the greatness of Xebec is no more and now they are doing mostly ecchi shows like this one and To Love-Ru. That doesn’t mean that they can’t reminisce about the old times by including old favourites in their new work, which is exactly what they did here. Ruri Hoshino appears in the world of MM! as a dakimakura.
As far as I know, dakimakuras didn’t exist during the time that Nadesico was at its peak so I’m almost certain that I can’t just go online and buy one, though I wish I could.
So in a nutshell, MM! is a total waste of time. The anime loses focus early on and drifts into random side stories, characters are not very well-developed, and there are only a few truly entertaining scenes once you get used to the silly personalities. Even fans of ecchi anime would be disappointed at MM! considering it has very little fanservice beyond the occasional panty shot and cosplay. Unless you really enjoy seeing a guy get beaten up by a bunch of girls and enjoy it, I would not recommend this anime.
