This is the late Roger Ebert's review of Being Elmo: A Puppeteer's Journey (2011).  And he gave it a thumbs up.  This was 2 years before his unfortunate death.  Roger Ebert, along with Gene Siskel were such great movie critics, and they together had such a great movie review TV show.  It's just too bad that both of them are gone forever, but however, they will never be forgotten.
