YMMV / Clockwork Planet

• Best Known for the Fanservice: The anime is now mostly known for the first episode's infamous "registration" scene, where Ryuzu visibly sucks Naoto's finger when confirming him as her master. (To be fair, though, this specific moment was present and unremarked upon in both the original LN and later manga adaptations).
• Just Here for Godzilla: In Japan, at least, the anime was received more favourably - mainly due a popular Japanese music duo called After The Rain performing its ED. The ED, "Anti-Clockwise" - as shown on YouTube - currently has over 3 million views and around 68,000 likes.
• So Okay, It's Average: After its airing, and with reviews having settled down - the anime is now generally considered as this; with ratings of 6.57 (out of 10) on MAL, and 3.2 (out of 5) over on a comparative Japanese review site, Anikore.
