I wasn't looking for a heavy, hashkafa/machshava shiur. I wanted an enjoyable series to keep listening to as I go about my day, but I also wanted it to be educational. This is perfect and I'm really enjoying so far. I feel like I'm refreshing my knowledge of Tanach and doing something good with my mind.
Thanks, OP, I always feel that I should learn Nach better after having not paid much attention to the already small amount covered in grade school.
Another thread here linked to raizelreitshiurim.wordpress.com where I really gained a lot from the shmiras halashon series (I finished the ones on the website but I hear there is a way to continue the series by phone.) They're so practical and relevant, and it's organized by things like character traits rather than a sequence of laws, so it helps you work on it in a realistic way.
