Apart from technical errors in episode 8, season 2 was great
I must applaud Silicon Valley for making the second season as enjoyable as the first (and including knob gags - whiteboard in season 1, monkey in season 2 - for laugh out loud moments). Perhaps season 2 episode 8's tequila bottle technical errors were the worst out of all 18 episodes, but that doesn't diminish that this is the best TV comedy I've seen since the much-missed 30 Rock finished (another lampooning insider show).
BTW, season 3 has some new writers and a new producer - see:

Hopefully, the show wil continue to keep up its high standards.
