Unlike other anime that try to fluff up the air time with shopping episodes, food porn and ecchi Maou starts off well. Initially I hoped they would cap the harem, which he acquired for no good reason other than "hey it's anime why not get some loli and oppai slaves". More girls are introduced because of course it's a harem so plot demands it.
Some episodes I felt like they were too lazy to animate certain scenes and just cut away and panned back when said animation would have finished. Like transforming with very little animation for half a second, panning away with flashing lights and ta-da transformation over. Just lazy animation and VA could have been better in some scenes.
Sometimes the comic relief is funny, sometimes it isn't. Fight scenes were decent and done in a creative way. Plot just kind of hops around and is not episodic but more like 1 plot per 2-3 episodes. It doesn't really have a real plot which is a downside that it has little potential to carry on as a story. But also an upside that it doesn't have to try to entertain you with a half hearted attempt at plot or throwing in something at the end to leave on a cliffhanger.
In short expect ecchi loli oppai slave harem. And rejoice that Maou he isn't another overpowered Isekai character and he doesn't always get an easy win just because he's the lv 150 demon lord with hacks.
Hope this helps.
