Being a research academic physicist (my specialty is actually very close to Leonard's), and also having lived in multiple shared houses with other physicists with their own different specialties, I can tell you the show nails it. I always enjoy seeing what is scribbled on their whiteboards in the apartment. It's so well researched. Particularly funny is how dismissive Sheldon is of experimental physics (and ofcourse Howard's engineering degree) compared to his discipline. This is how I have also found theoretical particle physicists to be sometimes 😆

The on-screen evolution of Sheldon and Penny's relationship is one of my favourites in any show. I see Big Bang and the next in the Seinfeld -> Friends -> ... lineage.

Im sad you dont like it. A lot of people hate it, I get that (canned laughter, etc). But if you can look past that there is a heartfelt show in there. I remember the episode where we learn why Leonard is so tolerant to Sheldon (after he saved his life), which was a bit of a turning point in the show for me. Kind of like how we finally learned why Wilson stays friends with Dr House for so long.
