Currently I'm watching all seasons of Mythbusters for the first time without the weird German dub. It's much more fun this way.
For everyone who hasn't heard yet, BBC's Sherlock is just worth a watch. It's a modern version of Arthur Conan Doyle's Sherlock Holmes (obviously) and Daniel Cumbercatch is playing the part of Sherlock perfectly. I dare say he's in the top 3 of the best characters on television right now. Give it a try or you'll regret it.
