I'm one of those who still like shonen and some isekais. XD
My favourite genre is Sci-fi/Fantasy and I love to dig through all kinds of shows like that.
I'm an anime fan for almost 4-5 years. I hate all elitists who always hate mainstream animes not considering their actual quality.
My ratings are based on 50% enjoyment and 50% quality of the show itself.
10- A masterpiece. Gem of an anime that is a must watch for every anime fan.
9- Not a masterpiece still excellent. Has some plotholes or cliches here and there but doesn't matter. Recommended to watch it.
8- Not excellent but very good. Maybe some part of the show is not that good but every other parts are very good. Again recommended to watch it.
7- It's good or at least a part of it is fascinating. Recommended to watch it only if you're interested in the genre.
6- A fair anime which has equal number of pros and cons. You're recommended to try it out but you may/may not like it.
5- An average anime. Probably an anime with a lot cliches. You're recommended not to try it out but you may/may not like it.
4- Bad anime. Stay away from it.
3- Outright bad anime. Don't even think to come near it.
2- Horrendous anime. You'll have seizures if you watch.
1- A mistake to humanity which we all have to burn out to achieve salvation.
