+Fast pace, no fillers
+Every episode has something unpredictable happen
+Memorable and likable cast of characters
+Good acting from mains, especially the ML
+Humor mixed with serious moments
+Good soundtrack

-Soundtrack is occasionally too loud and in your face
-Some of the overacting and dramatic camerawork fails and gets cringe instead
-The overall cartoonish style of characters talking to themselves, punching walls and being overexpressive might not be for everyone

It is, however, fine with me and I enjoyed Tengoku to Jigoku a lot.
