Plot is overrated. I like to watch shitty anime I can go into with low expections. I only friend people I have at least talked to. Check out my reviews!

Ultimately everything is based on enjoyment:
10/10: A show with a very strong appeal. An enjoyable watch through and through, with no boring sections. Something that connects with me emotionally, making it special. Any and all flaws that might be present are negligible. Something that I think back on periodically and want to watch again in the future.
9/10: A show with a very strong appeal. Shows that I think back on fondly and would readily suggest to other people. Shows that managed to surprise me. These possibly have minor issues with plot, characterization, art, themes, cohesion, have weaker archs or lack a satisfactory ending, which slightly takes away from the experience.
8/10: A show with a strong appeal. These can be consistent, enjoyable and unique shows with very few flaws, that for some reason don't move me on a personal level as much as other great anime. These can also be otherwise generally great shows that have noticeably weaker segments.
7/10: An appealing show. The baseline for a recommendable show. Consistent and enjoyable shows that do not quite wow me, or quirky and unique shows that have major drawbacks. Good characters and good character moments or strong thematic intrigue often grant this rating. Shows that have strong positives that are too thinly spread.
6/10: Shows with appeal that either don't draw me in, or end in a disappointing way. Shows that are not for me. Interesting but ridden with problems, which often emerge only later into the show. There is certain entertainment value, but I would rather spend my time looking for other titles. Possibly a guilty pleasure.
5/10: I don't feel a connection. These shows are barely passable, and lack any intrigue. Poor characters and character motivations can sink any show to this rating. I wonder what made me pick these up in the first place?
4/10: Something regrettable. A show's ending has to be a total fuck-up for me to have finished it.
3/10: Even worse than bad. Insultingly bad writing and/or directing. Something I begrudge every minute spent watching.
1/10: A special place reserved for the most abominable anime I have seen. There is no way I can handle even a single episode of whatever gets this rating.
