Since you mentioned "WebDL," I will quickly clarify the quality before diving into the review. A (Web Download) release is generally excellent quality—it is a clean rip from a streaming service (like Amazon Prime Video). It is superior to a "WebRip" (which is often screen-captured) and is virtually indistinguishable from a Blu-ray release for most viewers. You are getting the best possible visual and audio experience for this show.
If you meant something else (e.g., subtitles, episode list, release dates), let me know and I’ll help with that.
