I know there are people who'll say this show is unoriginal and dosen't do anything new or ground breaking or exciting, but the problem with anime is that there's so much different anime and manga out there that it's hard for a any show to stick out unless it's so big name or some new trending show like Mob psycho 100 or Twin star twin star exorcists, witch both of those are great but there do exist anime that is good just get shoved of as unoriginal and meh because critics don't want to be bothered with having to review them because they don't do anything new. However it's not also something new that makes your show stand out it's the execution of it and Mar dose good execution. Ginta, Babbo and the rag-tag group of friends they team up with and fight along side with are interesting, enjoyable and have their share of funny moments, the animations is pretty good, The music isn't anything super duper but it's pleasant, the plot has charming and is very fitting for this kind of show and the fight scenes are cool. I really like the ARMs witch is the weapons the use to fight in this show, they require the users own energy to use their special magic attacks and are ranked by class like holy Arms, dimension ARMS, Darkness ARMS and so on, It's kind of like the NEN chart From Hunter X Hunter. I will say the tournament battle arc does drag on but they change locations on where they fight witch really helps for any tournament arc and I do have to complain about the use of CGI but it's not as bad as say Kirby right back at ya. Over all I enjoyed MÄR Heaven and if your interested in checking out underrated anime I say check it out! And check out the Sequel manga Mar Omega.
