I am an absolute sucker for romcoms. (I'm not kidding. 90% of my anime list are romcoms.)
A wise man once said.
"Of course, as a man of culture. I cannot ignore the allure of a flat chest. It is only in such form that you can truly appreciate the budding tips. However... large breasts also come with their own allure. While flat chest would be a bud, large breasts are in full bloom. To be engulfed in them and receive their nectar is one of the greatest desires of man. Both are extremes in their own right. Both are scared fruits, and both are beautiful. So then is it not better to receive both?" -Nidome no Jinsei wo Isekai de - Chapter 26.2
Types of anime that I absolutely refuse to watch:
Any anime that goes longer than 70 episodes in a single season. (Too difficult to catch up and filler problems)
Any yoai / shounen ai (The reason is pretty obvious)
Reverse harems (It's pretty hard to enjoy if you don't find the female lead good.)
The entire SAO franchise. The abridged series is an exception. (Just no.)
Shows that throws fanservice just because with nothing else to offer (Unless it's self aware. Why would I want to watch a trash fanservice show when there is hentai available?)
Idol genre (I don't understand the appeal AT ALL. I mean yeah, their songs are great, but anime? it's boring as shit.)
"The perfect human male MC". They have 0 flaws and gets all the girls because "OMG HE'S SO STRON AND SO KIND IM SO WET AHHHH" (They never grow. They never develop. They are one of the most tasteless characters in history and do not exist in real life, ever.)
Almost all of the anime I watched have mini-reviews. Be sure to check it out on my anime list!
My rating system (highly depends on my taste, and if you feel offended in my opinion... then what the hell are you doing here? Go do something else!):
10/10 - Masterpiece
What I personally consider as a masterpiece. I can completely immerse in the show or scenes that I can relate to in real life. The amount of work and thought put into the anime would be monumental.
9/10 - Great
What most people (emphasis on most) consider as a masterpiece. The ones that I can watch it a thousand times and not get bored. Ever. Character development and story are done spectacularly. It gives a unique vibe that cannot be found on any other show. Anything from this score and above is a must watch.
8/10 - Very good
I would be able to recognise which anime it is by just looking at a screenshot of a scene. It shows concepts of what new animes can be or should be. I'll usually rewatch those series.
7/10 - Good
An anime that I enjoyed. It might suffer from a few minor problems that I can ignore.
6/10 - Fine
The default score. There are a few good aspects of the show, but still, suffers from flaws such as plot holes and weird character decisions that I cannot ignore.
5/10 - Average
"¯\_(ツ)_/¯ " sums up my opinion of this anime. Series where I just have no opinion, or painfully mediocre or generic will also fall into this category. Nothing strikes as unique or memorable. I would most likely forget everything happened about the anime in less than a day.
4/10 - Bad
Animes that have a flawed plot or terrible world building. These are shows that I usually half-way or wholly completed but took a massive grain of salt.
3/10 - Very bad
Where there are severe problems with the plot and characters. Many fundamental issues such as pacing, unused expositions are apparent in the anime.
2/10 - Horrible
Where the plot and characters stop making sense with cliches all over the place. The world building doesn't make sense (Things such as background story does not match what the world looks like). The differences between scoring a 2 and a 1 are down to enjoyment.
1/10 - Appalling
An anime is appalling when the show just offends my mind, and I hate it with a passion. There are no redeeming qualities. Where the world building either doesn't exist or doesn't make any sense. Characters do not make sense. Etcetera. It is so bad that you cannot even laugh at or find jokes in it. Just stay as far away as possible.
I just don't bother rating OVAs, ONAs, and specials (Unless they extend the story).
それはめんどくさいです ('Cause it's a pain to do so.)
