I think it is looking a little too much into reasons as to why the show closed. I think I have to agree most with Dancin Thru Life. It really wasn't one of those shows I wanted to make a repeat visit to (except to take my mom, which I ended up not doing). Okay, I was thinking about going again, but it wasn't on the top of my list of shows to see. I think most who wanted to see it saw it. If you like traditional, old-fashioned musical comedy, this show was for you. Although I liked some of the songs, I thought the music was overall bland and found myself skipping over much of the cast recording.
This is just my opinion, but I don't always let one song from a televised performance influence my decision on not to see a show. I haven't really seen that many stellar Tony performances in the past few years anyway.
Overall I give Curtains about a 6-7/10.
