I'm also finally giving this show a chance.
So far, about half way through season one, I'm liking but not loving it. The Hardy Boys in the X-Files universe premise is great, and i love the winky horror references. Just find the storytelling messy in execution, and the brothers as characters (esp. Sam) somewhat boring. (With the X-Files, Mulder and Scully were a captivating duo right off the bat, and with Buffy, the cast had a chemistry that clicked quickly. Angel comes to mind, that season one was really shaky) Dean has potential, but his JDness early on is unconvincing (maybe that's part of the point?). He's also not as funny as the writers think he is. So far, find the blue collar/classic rock soundtrack gimmick rather sloppy in selection and thematic relevance (and more than a few times, groan-inducing). Almost like the soundtrack is on random play. McG's staff doesn't exactly have the QT/Scorsese knack, that's for sure.
This said, the potential is there. I'll stick with it for at least a little while to see if it elevates in quality as much as most of you believe. If the ambitious mythology arc avoids the pitfalls, and plays out less tortured than the X-Files, I'll definitely be impressed.
