Honestly the show has the worst main character in all of sitcom history. Sheldon has a terrible personality and never get's told no or else he will throw a tantrum. Also he is definitely autistic. Mary has her good moments but overall she ignores her other kids. And treats Sheldon like he is the most important person in the world. Missy was a personal favorite of mine in seasons 2 and 3. But had a downfall in the last season. Where she is just rude. But Georgie, George, and Meemaw are still decent.
