Mecha: If there are only mechas yes, if starts to mix genres NO, I like to see mechas fighting or engineering implied, not a kid screaming a x character in the middle of the first episode just because is he was late.
Romance: It touches me very hard, in fact, the more realistic and relatable it is, the more chance I have to start crying for weeks (yup, i'm a cry babe)
Drama: (excluding Toradora!) Absurd drama that mixes comedy while they are in a scene where evidently it is not necessary NO. Outside of I like it since I feel able to reflect myself in the context and the environment, making it go into retrospectivblahblahblah
Gore: Nothing to say.
Josei: Most of the time i love just chill around y'know
Slice of Life: As long as it's not fantasy or something absurd. ReLIFE is an example of how it touches this that although it comes out of the real (by the pill) the context is very relatable and enjoyable.
I hate isekais since all of them (or mostly i saw) are just Gary stu over and over with the same context, avoiding the comedy or the action itself that they can actually bring, it just...
Hate Harem, just an excuse to see bobs, even if you found 1 pretty neat, next to you only find trash.
Yuri because most of them just instead of balance the romance with (insert any kind of mix genre) it just go for te free kiss/fanservice.
I like so hard Strawberry Panic btw and most of the new yuri s**t had to learn about this one.
Ecchi... i had to explain?
Dementia because just manga can fit with (my opinion)
Horror because is the same as Dementia but more soft at how it affects/trigger me
