Gore for the sake of gore when it is done in a humorous and intentionally over-the-top fashion such as the ending of "the Substance" or basically anything "Evil Dead" related is fine, and the gore in "Saw" was nice and really well-executed until they made 37 of them. Horror is a tough genre to pull off in an innovative and interesting way. "Smile" did a pretty good job of it.

It's been a long time since I watched any of them but I vaguely recall enjoying 1 and 2 but when it came to Saw 3, it went too far.
