I really don't understand why this sitcom has a high rate because I didn't find it funny or entertaining at all. I started watching it because people kept admiring it and I regrettably watched it all in a month of being unemployed and not even once I laughed.
The worst thing is the terrible characterising.
Raj is so annoying and nothing to like about him. Howard's also one of the characters that can make you hate the thing. Penny's actress is horrible and if you wanted to choose someone close to the character, scored! Bad actress.
The only good thing is Sheldon and Leonard's actors who have been great on building the character.
The plot is interesting but it's ruined with the bad characterising and casting.
I'd rather watch "Friends" for the thousandth time or "How I met your mother" for the hundredth time instead of this. I don't think they will be able to make a sitcom like them ever again.
