English is not my first language, I'm still learning! :)

My ratings:

8.5 — I loved it, and I enjoyed watching even though I see some flaws. The general vibe was awesome, but not always that strong.
9.0 — I loved it very much, I enjoyed watching, and I see (almost) no flaws. The general vibe was wonderful.
9.5 — Literal masterpiece. I didn’t know such diamond could exist.
