I enjoyed it, but they could have done more. I imagine it's hard to wrap up something that has 11 years of storyline.
It's a better ending that Sopranos had, and dare I say could be better than GOT will have.
That said, the Young Sheldon spinoff is a good show. I hope that keeps going to explain some of the stuff that was not explained in BBT. It really fills in the backstories.
