this show is the best show i have ever watched each and every episode shows how talented every person who plays the role is even though sheldon is the main attraction of the in my perspective the show without leonerd and penny would be incomplete as well as amy who influences sheldons life.This show shows a lot of bonding and how a family lives together and shares each others happiness and sadness together.while howard being funny and amazing freind in need as well as raj.SAD THAT THE SHOW IS ENDING A BIG THANKS TO THE BIG BANG CAST FOR ENTERTAINING EVERYONE
