Not an expert by any means. Really put off by the dipshit Bro mentality that ruins so many of the most popular ones. Here's a couple I like anyway.
I'm pretty into movies so I really dig on The Next Picture show (
http://thenextpictureshow.tumblr.com/). It's the folks that used to the dissolve podcast back when it was around. They take two movies, one old and one in the cinema at the moment and dedicate an episode to each comparing themes etc etc. Always great. Smart folks saying interesting stuff.
On a similar note, these guys have been going for years and are still great. Filmspotting (
http://filmspotting.net/) Like 11 years worth of archives there so plenty to look back on if you have an interest in movies. I listen every week and go back and check out old episodes all the time. Really good stuff.
This might be a little more niche but there is a football ("Soccer") thread on here so thought some of you guys might be into. Maybe I'm biased coming from Ireland but these dudes (
http://www.irishtimes.com/sport/second-captains) are the absolute best at what they do. Just smarter, funnier and overall better than other english football podcasts. Their non-soccer show is available there too, Covering all sports (NFL, NBA, MMA, Olympics etc) though they usually have a section on Gaelic Games too which I doubt means much to anyone outside of the country. Football show is absolutely worth checking out for anyone with any interest though.
Shout out to The Bunt too. By far best skate podcast. Chris Roberts has been a favourite of mine for as long as I can remember but dude really needs to stop asking people about their fucking instagrams...
