I've noticed all of these things, too, but I've also noticed how much they've changed Sam and Dean--especially Dean, and I no longer love them like I once did. I think I've fallen out of love with this show now. It's pretty sad that I'd rather watch reruns of That '70s Show (which I only just discovered a week or so ago *g*). Maybe if it gets better, I'll regain my love for SPN.
