Really glad to hear that other people are liking it! I think the Christmas Carol comparisons are working well.
It's hard to get my memories of the Broadway production out of mind, but per usual SF Playhouse does a really good job. I agree with all the praise for Ryan Drummond. The last two things I saw him in were Sunday in the Park (Jules) and La Cage aux Folles (Georges), and I was impressed with his ability to play against type. My main worry going in was whether the show would work without Andy Karl. Ryan isn't Andy, but he carries the show and gives a heck of a performance. For those curious - compared to Andy, Ryan's Phil is a little less grand and epic in the mania of Act I, and then the despair and enlightenment of Act II. Ryan comes off as more human (albeit still a real jerk in Act I), but when he finally becomes a decent guy, it's moving in its own way. (If anyone *has* seen both productions, I'd love to hear what you think).
The smaller theater space makes the sleight-of-hand stagecraft all the more impressive, IMO.
Re: Standing ovations, I went for Round #3 on Tuesday evening (Look, Groundhog Day is my favorite recent musical, tickets are affordable, and it's easy to get to the theater from work). The audience seemed to enjoy it, but there wasn't a standing ovation. I *wanted* to stand, but I felt awkward being the only one, or being the one to start it.
