I tried watching Fringe, but I hated the characters right off the bat. "Doc Brown", his wisecracking son, and the chick nonchalantly solving weird mysteries with no sense of danger. No fear, no "holy shit, aliens." It was just another day. Completely unbelievable characters. It was like watching Charmed. No matter how big the threat, the witches didn't give a fuck, and they were never in any danger. "oh you're an evil demon who can destroy the world? Let me talk some shit."
I never made it passed the second episode, so things may have changed, but I did not like what I saw.
I didn't actively watch Charmed. My girlfriend loves the show, and I only saw it in passing. That show is awful beyond words.
I love The X-Files, but I still have a couple seasons to go. John Doggett is a cool character, but after David Duchovny left the show it was harder to stay interested.
