    I think the show is getting better as they progress in seasons as to other shows that get worse as they move on

  2. Hardywolf359 says

    Cancel Big Bang? Oh good Lord! Are you insane this show is up there with Cheers and Taxi and will be remembered alongside them in decades to come! Don’t let this be the Firefly of comedy shows! If the Simpsons can run for over 20 years (and that has lost it’s funny bone a long time ago) then this one can go for at least 10. Live long and prosper!

  3. andreaaaa says

    This is easily one of the best shows on TV. Jim Parson’s is right on point as Sheldon. Definitely worthy of his Emmys. The writing is genius, and the formula for the show flawless. Hope this show stays on as long as possible.

  7. Louis says

    ^ Oh, shut up. BBT has definitely held its own over the seasons. The introduction of Amy and Bernadette has been seamless and perfect for the show. Consistently funny, entertaining, and even educational at times. De-bunch your panties. Thanks.

  8. Manigran says

    I used to love this show, but lately, it has been going downhill. I’d like to see it cancelled so that no more damage can be done. Thanks.
