There are some tiny spoilers ahead but I am open overall*

This anime was not suggested by anyone to me but rather I found it through the trailer by mistake. Ains looked interesting enough so I started the first ep and at first I didn't like it as much but after a certain time it grew upon the characters and the story. At the end of season 1 I was ready for more and completed season 2 in two days with speed. Season 3 was also good and I ended the show in like a week which can tell you that I liked this show and was a unique take rather than normal isekai but It was more like SAO but better for me because overlord didn't made it into a harem which SAO did.

Animation:

It was an op animation style which I liked it from the start and madhouse did a great job with this. I have watched Redline movie after the overlord and I didn't know that both these were created by madhouse studio. I found it just while writing this review and I am a bit shocked yet glad that I watched both of these. If you have watched any of the shows or movies from this studio you will know what quality animation they create.(8.5/10)

Characters and Timeline:

The characters above all had unique designs and the behaviours of them were fitting. I loved Sebas as a whole and grew up on me in the 2nd season which I liked. The story was super good and throughout the story ains was overpowered but I was more interested in other people's perspective about him. Furthermore, this made the world more believable and close to reality well not real real but good enough. And people with him some I liked some I hated. Demiurge, Sebas and the twins I liked and I didn't like albedo as much and the vampire girl was alright. (9/10)

Openings and soundtracks:
Ok so openings were super good and fitting for this show. Voracity (OP 3) was my favourite and then OP 1 and then OP 2 the endings were good ED 2 was my fav. The same things with the soundtracks and the background music were very cool. I could definitely listen to these songs when I am doing something.(8.3/10)

Other things I liked:
The creatures were interesting which kept my interest sometimes. Ains is more than a skeleton a was very menacing at the start and I loved it. Background were not bad but in my opinion the characters were more interesting.

I talked about Sebas and how I liked him well it happened when he met Climb and Unglaus (can't remember his first name my memory is a bit rusted) and the girl he found so on and so forth. He is a gentleman with his unshakeable resolve and you can't change my opinion. This were my opinion and I am really glad that I watched this show. Can't wait for season 4 and the trailer looked promising hope it doesn't disappoint fingers crossed....
