I would also recommend Curb Your Enthusiasm, but there is a difference: Larry David is neurotic, but even in his fictional Curb Your Enthusiasm persona he is extremely wealthy and successful. That is a big difference from George Constanza, who combined being neurotic with constantly being adrift employment-wise and has little to recommend himself.
Yeah, but if you like Seinfeld in general there's a good chance you'll like 'Curb Your Enthusiasm'. Seinfeld has a higher 'standing' in my personal ranking, next to friends it's my favourite series to date.
If you like these shows and your sense of humour is similar to mine, you might also enjoy "Friends" and "How I met your mother". They all have a similar feel to me.
I hear this all the time, and it just doesn't click for me. I liked Seinfeld, but Larry's character on Curb is just too much. I also love It's Always Sunny... but I just cannot enjoy Curb.
