NBC’s staging of “The Sound of Music Live” predictably became online water-cooler TV, generating a steady deluge of Twitter commentary. The observations ranged from snark to swooning over the classic tunes featured in the beloved musical about a nun-turned-governess who helps an Austrian family learn to sing and escape the Nazis.

A few studios banked on a big turnout for the tuner starring Carrie Underwood and Stephen Moyer to serve as a platform for pic ads. Disney gave a big plug for its “Mary Poppins” tale for “Saving Mr. Banks” (make that three), while CBS Films’ pushed its Oscar hopeful “Inside Llewyn Davis.” There were also blurbs for “The Secret Life of Walter Mitty” and “Frozen.”

For the live East Coast airing, there was plenty of criticism about Underwood not being up to snuff for the lead role and the production not measuring up to the 1965 Julie Andrews pic. And there was chatter about the lighting leaving scenes looking a little dark and the orchestra being too high in the mix.

At the same time, NBC and the “Sound of Music” troupers garnered kudos for sheer ambition and derring-do with a live broadcast that more or less went off without a hitch — or at least a noticeable on-air stumble.

Here’s a sampling of Twitter reaction to the telecast:
