Although,there are quite a few similarities between the two but it'll be unfair to judge on the basis of that.
On one hand when "OPM" was eye captivating from the first episode itself,"MP100" is paced bit slowly and takes the time to develop but once its reach the peak,it's quite enjoyable.
-PLOT-
The story revolves around 'MOB' a middle school boy who is gifted with psychic power from childhood but as he grew up he realized how dangerous his power can be if misused,so he started working under a fraud self-proclaimed psychic known as Reign Arataka who takes advantage of him, to earn quick cash and this is how MOB's adventures goes on,he also got a crush on his classmate and tries his best to impress her but being socially inept,all his effort end up in futile.
The story is pretty decent and gets better with each episode and despite how we feel about the animation,the action sequences are top notch and one of the trait mark of "ONE" works but the comedy aspect is a big let down,all I have experience is cockroach,porn and all sort of lame and body shaming jokes.
A bit of them was humorous but the majority of them aren't funny at all.
-CHARACTERS-
Mob- The main protagonist of the show,a boy who wants a just little bit more from life and doesn't feel proud of his gifted psychic strength.
Reigen Arataka- Mob's mentor,a cunning businessman and 100% troll to remember the name.
Hanazawa teruki- With the introduction of this character,it gave a major boost to the show overall.
Who doesn't love a friendly rivalry?Kanazawa is like Vegeta of this show.
Kageyama Ritsu- Mob's younger brother who looks almost identical to him, the only thing that separates him fro, Mob is his spiked hair.
Despite having all the things a boy would want at his age,he's always having an inferior complex to his Mob
Few of the characters, in the beginning, were really annoying and they still are but after the addition of characters like Kageyama and others,it's really got entertaining.
-ART-
At first glance,the art may not be appealing to all eyes and there is no wrong in it,you may still admire or despise it and that's got nothing to do with having a bad taste as each individual is different,
-SOUND-
There's nothing much to talk much about this section,the opening is quite dynamic and the tone in each episode is fine.
-ENJOYMENT-
Due to the nature of the show,I got a bad impression after watching the first couple of episodes but when I continue with the later episodes,I was amazed to see how much better it can get.
-OVERALL-
It's a pretty good show but its got the flaws too so if we can keep that aside,it's worth watching
