I recently acquired Supernatural based on a few positive mentions here on KIA2. I quite like it, but it's a bit... off. These sorts of shows are really about the banter and camaraderie, with the monster stuff being almost incidental. Somehow the chemistry/banter is not quite working for me.
Should I persevere?
That's fair. I think their biggest problem was a lack of really utilising the villains they made. The Styne's were an amazingly interesting idea, and for them to have lasted a grand total of 3 episodes (over a grand total of a 5 episode span) did them dirty as a concept. It had potential, and then it was gone before it could be used.
That's probably the biggest issue with later Supernatural, a weird choice of which villains they chose to focus on. They had the Styne's and chose to focus on Rowena. They had Dagon, and chose to focus on the British Men of Letters. They had Asmodeus, and chose to focus on the Alternate World. It just felt like weird priorities.
I know it sounds like I'm downplaying a lot of it, because I liked Jack and there was a lot of potential with so many other characters or concepts, but then it's no explored and it's more annoying because now it feels wasted. Everyone who I know liked Supernatural and kept watching loved the idea of the Styne's, but they only last 3 episodes. It was beyond wasted, and it's not the only concept that was wasted. And I think that's what annoys me most, was just how much was wasted in favour of lesser ideas.
