For James Bond Radio, I would start off with one of their film reviews. Next Friday (June 5) they'll be releasing their review of The Spy Who Loved Me, and they've already reviewed all the Bond films that chronologically preceded that one. JBR also does a lot of interviews with people associated with the Bond books and movies but I personally don't find those as enjoyable to listen to as their film reviews.

For Get Off My Podcast, I really liked their review of Raiders of the Lost Ark. It was entertaining but also extremely informative, I learned a lot about the making of that movie while listening to it. All of their episodes are pretty awesome if you're a fan of Harrison Ford movies, though.

For Mad About Movies, the two episodes that newcomers have to start with are their reviews for Now You See Me and Draft Day - the hosts reference these movies (and their disdain for them) quite often. Stop The Movie did really great reviews of Die Another Day and Batman & Robin not too long ago, so I would start there.

With Mancave Movie Review and WTF Are You Watching, I can't really think of a specific episode that you should start with. They both have pretty extensive back catalogues so just go on their websites and download whatever strikes your fancy. You're bound to encounter a review of at least one movie you like on there. WTF Are You Watching will be releasing a review of Indiana Jones and the Temple of Doom on Monday morning, though, so there's that to look for if you like.
