Well made? Even disregarding the source material, the pacing is horrendous, the characterization is a mess, and the plot isn't even interesting. Sure the acting is good but that's about it. I need more than "good production values" to keep me entertained. I honestly don't even know why non-comic readers enjoy this show. It's terribly boring and the main character is an insufferable, unlikable douche.
Plus, the appeal of Preacher is in its unapologetic combination of blasphemy, violence, sexiness and over-the-top craziness. Quite literally the opposite of what we're getting, outside of the occasional Cassidy scene.
This is all subjective of course, but I find the show fresh and atmospheric with great characters and good casting. It isn't the most frenetic, pounding, fast paced show on TV, but it has the violence, blasphemy, and sexiness. Lots of gore and bloody fighting, almost every episode. Cassidy is great and Jessie is a basic antihero struggling against his demons but in a fresh wrapper. I like Tula and all the other characters and enjoy all the craziness. And some may think the establishing shots are a bit long, but I think they serve to build an atmosphere of tension and dread while giving the show a distinct vibe. I don't know what you were expecting but I love it. I'm ok with having an unpopular opinion, so it's cool if you don't agree. This is all subjective.
