I'm a comedy fan but somehow both Steve Martin and Martin Short have escaped me. As someone who's never experienced their comedy, I had a truly pleasant experience. They have a great comradery and bounce off each other well. A little over rehearsed at times, but it made me smile and feel a little warm inside. Martin Short's impressions were excellent, and whilst his physical comedy doesn't always sit well with me, his 70s style comedy transcends the ages. Steve Martin almost seems a bystander to Short's comedy at times, but his stories make up for it (as the far better storyteller).
Overall, it's a pleasant watch that is nothing like today's comedy. Apparently these two comedians have influenced today's prominent comics, and you can tell. Louis CK gets his story style from Short, Gervais pulls from Martin's intelligent wit and self deprecation. As long as you expect an understated experience to enjoy two people working well together, you will have an entirely pleasant experience. 7/10
