I enjoy romantic comedies and slice of life shows most, but I'm mostly looking for something entertaining.
I tend to rate a little generously for most shows, but I factor in my enjoyment of the show. I've been very entertained by even mediocre dramas sometimes.
This is how I usually rate:
Score of 1: A fail and considered shit. Its creation is horrid, its ideas is a nightmare and its characters are a joke, wait, the entire series/movie is a joke.
Score of 2: Badly executed that leads to a drop. Probably made me fall asleep quite often.
Score of 3: It's most likely dropped before I continue watching further or I may end up wasting my time.
Score of 4: Somewhat ok but lacks flavor. May lead to a drop although depending on my mood.
Score of 5: Not bad but should be executed better. The word "meh" fits to this score.
Score of 6: Average, does have great points and considered watchable in its entirely.
Score of 7: Not bad, not bad at all.
Score of 8: Very good, and delivers enjoyment that can be described as fun, entertaining and easily watchable.
Score of 9: Excellent. May be considered re-watching with its powerful storyline, intriguing characters and superior soundtrack that deserve high praise.
Score of 10: Masterpiece beyond words. Deserves a high level praise that it gets with its near perfection.
