Cumberbatch, is, of course, motherfucking Sherlock, and also showed up in Tinker Tailor Soldier Spy and Steven Spielberg's Battle Pony, and he'll be Smaug in Peter Jackson's Hobbit movies. He is fantastic, as anyone who has ever seen Sherlock can attest (especially the most recent one, which how great was that), and this news is entirely awesome, which is why I have expressed more enthusiasm in this single paragraph than I have in real life for the entirety of the past three months.
BUT IT DOESN'T MATTER WHAT I THINK. Do yourself a favor and head over to the comments at TrekMovie, home to my favorite commenters on the internet! (After a few of you Blogtown residents, I guess.) The thread is full of comments like this one, which, obviously, speak for themselves.
