A likable protagonist? In my isekai anime? It's more likely than you think.
In fact, our hero's likability is pretty much what saves Overlord from becoming a huge bore. As Momonga, Satoru Suzuki is extremely overpowered, as you might guess from the show's title. Time in and time out, he manages to use his gaming prowess to defeat his enemies.
Thankfully, the show manages to be less like another No Game No Life and more like One-Punch Man in this regard; under the overpowered skeleton surface, Momonga is a genuinely relatable everyman. He's the kind of dork who communicates with his fellow players using cartoonish smilies that contrast with his creepy avatar and spends the last day of his favorite MMO's existence screwing around with all the power he's amassed throughout his time playing. Seeing him so all the silly, sentimental things I could see myself doing if one of my favorite games was closing got me firmly on board with him as a character.
That's not to say our hero, along with Madhouse's stellar-as-usual artwork and sound, can save the show from every single flaw though. One of Overlord's biggest issues is in its pacing. While earlier episodes go by at a pretty steady pace, the overall arc starts to slow down in later parts and eventually goes full on One Piece shonen battle pacing by the end. While you might be able to tell from One Piece being firmly placed in my favorite anime that this didn't really bother me, I can see how it can feel slow if you're not the kind of viewer who is used to it.
As far as genres I'm not as big of a fan of there are also times the show teeters towards becoming a harem anime, with scenes where female characters argue over the usual harem crap. This was annoying and honestly felt kind of out of place with everything else, especially with Momonga himself being uncomfortable with it.
Another shortcoming of the anime is standard for the isekai genre at this point: the world of Yggdrassil is just your very bland, standard MMO. There's not much to see that's unique here.
Overall, while not perfect, Overlord pleasantly surprised me. It's one of the first Isekai anime I've watched where I honestly related to the protagonist, and I enjoyed the shonen elements. I look forward to catching season 2 of this show in the future.
