I second your feeling about Big Bang Theory, but I don't think SV is that bad. Personally, I liked the competing show "Betas" a lot better because it had subjectively more soul and better dramaturgical timing, but other than that Silicon Valley is mildly entertaining. Compared to BBT there is not a lot of pretentiously presented flavor text with at best a tenuous connection to real science, so I think Silicon Valley might at least have better expert consultants than most professional-themed drama and comedy shows. That still doesn't mean one can or should expect total factual accuracy from a TV show, it's still just entertainment - it just has to be enough to make you believe for a few minutes.
