I've been listening through the back catalog of this podcast recently and have been having a blast doing it! The hosts take a lighthearted approach to the movies, but also take them seriously and provide solid analysis of their strengths and weaknesses. It's a neat trick -- they have the ability to make fun of a movie while also treating it with respect. (Their treatment of ZARDOZ one episode that comes to mind in this regard.)
I recommend starting with an episode about a movie that you love, and then continue digging in with the most recent episodes.
