The Big Bang Theory stopped being funny completely after few seasons.

Don’t get me wrong, it started with a totally killer humour, you didn’t need to be an expert about every scientific fact or ocean of comics/sci-fi series, it didn’t surprisingly get too mean-spirited but that was about it. It had a great balance of everything and the lines were gold.

But then everything changes. Nothing against letting the characters grow up a little, it does a rather good job at this. But the humour was forgotten. The laugh track’s reaction ability became a total shadow of former self. Remove it and you don’t know where to “laugh”. Tim Allen’s various grunts work better than classic laugh track there (thx YT).
