Pushing daisies. I swear no one has ever seen this show. It has everything, it's dark, it's funny, it's absolutely beautiful aesthetically , it has one of the best romance plots in any show I've ever seen. The show follows the pie maker, who can bring people back from the dead by touch but only for 60 seconds before another life is randomly taken. This meets with hijinks when he teams up with a private investigator in a dark whimsical world.
I stick by the reason it was cancelled is because it made every other show on the station look like shit by comparison.
Also if you want to get your depression on, carnivale. Another stunningly beautiful show that shares the healer at a cost theme. This show is not funny or happy though.
