Most shows have one, come on. Web novels have wiki pages for damn sake.
I do want to say, that I also love this series, and I am watching Fire and Brimstone right now in 5 minutes for the 4th time. After that is the Great Red Dragon, followed by "Red John". Ugh, good stuff, really good stuff. It's not the same after that for the rest of that season, but the next one is pretty good. Satisfying
I watch it via a streaming website that is free. I won't post the link here in fear it will be taken down somehow, but just "google" the mentalist stream or so, and voila. 1080 P even, so it's good stuff. I have watched it once legally with the money, so I don't care one bit about the future times I watch it really. Just search for watch the mentalist online, stream, or something like that and you will probably find the one I am using at this very second
Best show ever? No, I can't say that. Is it one of my favorite series that I have watched 4 times over? Yes, yes it is indeed that good
