Yup - I admit it -- I'm a sucker for watching them.
I like Paranormal State because I like to yell at the god-boy host sometimes, and giggle. To me it boarders more on a show about the power of suggestion than anything else.
I didn't like the GH International show at all. In my opinon - poor investigations far too many easily explained phenomenon that were viewed as "compelling evidence"
I never used to like Destination Truth - but I think the host is funny and if nothing else is going on I will watch it...tho the fact they only investigate the creatures for a day or two bothers me.
Never seen Monster Quest.
You forgot to mention "Most Haunted" - Travel Channel...tho it is totally forgettable. In my mind it's the best for yelling at your TV.
I must admit the show that impresses me the most, and most frequently is still Ghost Hunters. I rarely find myself diagreeing with what they find, and they seem to be the most rational out of all the "ghost hunter" types on the air. They have had some evidence that still leaves me scratching my head. I am giddily awaiting next weeks episode to see what this 23-seconds of footage is all about.
