What anime would of have benefited from having fewer episodes?

I'll start: Scrapped Princess.

The series has bad pacing. The series just spends sooooooo much time spinning it's wheels with characters talking and expositing...but nothing is actually happening. Words are being said and conveyed...but the plot is not moving. Even up to episode 23 of 24, the first 12 of 24 minutes are just spent meandering with meaningless dialogue and banter that doesn't further the plot or add any real character development. If the anime had fewer episodes, it would be better off, like maybe 1/3rd fewer episodes?

The first 12 episodes are actually pretty good with pacing but the 2nd half is where the slog begins and the story just drags.
