What television shows were you excited about because the underlying story or idea was interesting but the acting, writing, or other aspects ruined the whole thing?

Partners (with Kelsey Grammar and Martin Lawrence).

I have a few;

Batman
I know 120 episodes is nothing to sneeze at, but the series ran for just over two years, and really ran out of steam during its second season. If the show had played it straight I think it would have had a longer run.

Good Morning, World
Great potential (Reiner and Leonard how could you go wrong), but I thought bad casting killed the show. Joby Baker was a not funny, and Billy De Wolfe, just plain annoying.

The Odd Couple (2015) Matthew Perry is badly miscast as Oscar, and all those extra characters, a complete mess.

Lotsa Luck
Again Reiner and Leonard, cast was good, don't know why the show didn't come together.

The Munsters Today
The cast (especially the three leads) was a pale comparison to the original cast members. The production company really didn't understand what made this show funny.

2 shows that are airing right now on have this problem one is last call on nbc its could be a great show but carson daily is a lousy host the other is handcrafted america on the insp network it is a good show but again like last call suffers from a poor hosting choice in jill wagner
