I wonder if this aspect of SMASH feeling like a show that starts slow and picks up is based in part on the NY Times review, although that said it picks up in Episode 3. This was from the NY Times review of SMASH by Neil Genzlinger:
" But it soon found its voice, and the audience found it. “Smash” gets better as it goes along. It’s unlikely to achieve television greatness like “M*A*S*H” did, but by Episode 3 it shows signs of becoming an addictive pleasure along the lines of this season’s “Revenge.” "
