1 Star = 1-2 Hated (Want the hours of my life back)
2 Stars = 3-4 Disliked (Wouldn't Recommend)
3 Stars = 5-6 Average (Don't regret watching or generally enjoyed, but didn't move me)
4 Stars = 7-8 Liked (Definitely Recommend)
5 Stars = 9-10 Loved (Have watched multiple times and adore)
Note: My personal rating system is tailored to my tastes. There are many animes I highly recommend or love for personal reasons that the general masses wouldn't agree with. They were key childhood favorites, watched during personal milestones or are simply pick-me-ups that I know I can go to when I want a smile or fun time.
The same applies to anime I rate in the 'hate' and disliked sections. Many times the anime simply didn't suit my taste or hit way too many of my personal squick buttons (be they character or plot contrivances) or were simply in genres I don't tend to like, but still tried and found personally wanting.
