This was eventually an OK episode, but the first half dragged and was pretty much laugh-free. PIcked up in the second half which was much better still without being hugely funny - a lot of setup which didn't altogether pay off.
The Raj drunkenness trope is starting to wear really thin - they need to do something with his character to move him forward - let him talk to women he knows well, at least - then he doesn't have to be drunk or mute in every scene.
As for the other scores - 10s? Seriously? There are no ways that this could have been better? There are no episodes in the previous 5 series that were better than this - S2 E3/5/11 for example, back when it was consistently laugh out loud funny?
