I might be in the minority here but I think the spin off is a disaster waiting to happen. And more seasons, as good as it sounds on paper is excessive to me. Cool, they're not going to throw money away and say "Hey we had a good run now let's go out on top", but I wish them luck coming up with enough varied content for two more seasons.

You really wanna see Leonard and Penny have the same arguments for 48 more episodes? You wanna see the same boring conversations between Sheldon and Amy? I don't.

The next two seasons cant be exactly like what we've seen this season for this show to go out on a high note. I would add characters to shake things up.
