I love Sinatra music and I admire Twyla Tharp so I was really excited to see this. Great dancers...especially the leads. Wonderful orchestra that played great background to crystal clear recordings of Sinatra's voice. But I dunno...it just didn't excite me. Can't figure out why...but it just did not mesmerize me. Add that to some of the most uncomfortable seats in Las Vegas and it all added up to two stars.
