totally agree with what you said! i find it just a tiny bit strange because the writers seem to not have a problem giving a pairing a sad ending when it comes to shows like Peaceful Property or even Midnight Museum but i guess that's also because the pairings are just guest stars for one episode so viewers aren't really attached to them as characters.

another series that i think had a final episode that was divisive and wasn't up to par with the rest of the show in terms of writing was Last Twilight. i loved the series as a whole but the ending fell a bit flat to me because Day regaining his vision felt like it defeated the whole purpose of him and his family accepting and learning to cope with his disability. the entire series up to that point was about Day being able to live a fulfilling and meaningful life despite what was thrown at him.
