I felt this version was a warmer one, especially because of the ending (that is, the ending without the pop song again). I haven't seen the musical on stage, just the original film.
Chris Diamantopoulos was new to me, and quite a song and dance man.
I know him from "Silicon Valley" but he was the star for me. I thought he was absolutely terrific. We loved the show when it was on Broadway a few years ago. I didn't love this TV version (I haven't loved any of the live TV musicals) - but I really enjoyed him. Thought he was terrific - made the part his own, but paid homage to Darren McGavin too.
