Nightmare came true as in the absence of masterpieces need to choose among above average works that I watched to the end. And I'd rather nominate serious Tengoku Daimakyou than ecchi harem.
After finishing Chainsaw Man , I decided that it's only getting a honorary masterpiece for the effort of change and any other masterpiece would beat it. And that honor goes to sequel Tiger & Bunny 2 Part 2 .
Mydramalist has thousands of doramas, so I exclude all those I can't find or equal/under 30 minutes length or under 3 episodes long or belonging to Detective or Wuxia or Sports or Boys Love, or sequels (unless only sequel gets subs), maybe some more blacklisted categories to follow. As expected, found almost nothing from the 60s and not much from 70s. Among the subbed ones only consider Ogon no Hibi (1978) a masterpiece.
Surprisingly adequate number of titles in February, so I could safely cut couple titles that would fit otherwise (notably, Alice49 EP.0 "Diamond to Shukurimu" and 5fungo ni Igai na Ketsumatsu Monochrome no Toshokan).
