I'm sorry guys... but my dissapointment can't stop to grow and grow.
Did you already read this crap?

..and look this part:
Simon, when you got the list of the final seven suspects, did you have your own theories about which one was Red John? 

BAKER:  No.  

HELLER:  He was holding out for Jesus or Elvis. 

BAKER:  I was hoping that Quentin Tarantino would show up on that list.  No, I didn’t have any theories, at all.  Actually, I made a point to not read too far ahead with the first six or seven episodes.  I would read the outlines, but I didn’t really want to read scripts too far in advance because I didn’t really want to get ahead of myself, at all.  To be honest, I don’t have the time to come up with theories.  

What??? "I don’t have the time to come up with theories. ".

Yeah. I just can say one thing: We're all idiots wasting time with this shit. I can't believe I lost more than 5 years with that. They really seem not care about us..at all.

So frustrating...I can't explain.
