There are plenty of French podcasts available on the site radio France (
http://www.radiofrance.fr/ ), and you can find podcasts series about basically anything (from politics to science to poetry) as it is split into different sections such as France Inter, France Culture, France Bleu, France Musique etc.
What you would enjoy listening to depends on your tastes, but I have liked listening to:

http://www.rfi.fr/emission/grand-reportage/ for news reports about what is going on around the world.
Most of the ones I have linked last for around an hour, but you can find plenty of shorter podcasts lasting for as little as 2 minutes. Also note that these podcasts are made for native speakers, which means the vocab, content and speed of speaking may be a lot more sophisticated than what you are familiar with. But even if you understand only a small amount, being surrounded by the language on a regular basis will improve your listening skills, accent and vocabulary. You can choose to use the podcasts as a 'study tool', listening intently to pick up vocab and phrases (which is an awesome way to learn), but If you're not up for that, that's ok. I recommend just playing it in the background when you're doing other things such as scrolling on social media, cleaning your room, on a bus trip home etc. and even that makes a big difference.
As for tv series, I can't say much on that end because I haven't found many series I like. French film, on the other hand, is really diverse and super easy to access online with just a quick search so you'll be bound to find something you like. Netflix also has a good selection of French films which you can listen to with french or english subtitles (best combination is French w French subtitles) which you can access by looking up French Movies.
