I liked it, and i think all fans will too. I am no more addicted to big bang :D
So many series to watch, so many films... Bazinga! I still awaiting all week for this :)
All actors came with energy and very 'in' characters. This episode is good. A special St. Valentine. Its 3rd season and they are making specials. Its very well written, all characters participate. Howard not appears so much, but this is because is very well with his girlfriend. Leonard is trying to put Sheldon out of his way and get the trip to Switzerland with penny, Koothrappali is dumpy with St. Valentine day arriving.
We can see 'Ow god sakes!' by leonard (thats aways make me LoL), Sheldon playing flute :D, Howard talking to bernadete on phone, Koothrappali depressed replics, Penny's face when she has invited to go see The Large Hadron Collider.. and much more fun.
Go see it. Cya.
