Hi Sophie (: It depends on your level and if you interest in british or amercan accent! On youtube you can watch teacher AJ hoge talked about how to learn english from movies its really helpful method. Try it!

It depends on your level... Or what you're interested in. I think Seinfeld or Friends would be good shows, as they are centered around average people's lives. Roseanne is also good, and would be good if you want to hear more slang. Big Bang Theory is really popular, but tends to use some scientific vocabulary that may be hard to follow.

Try www.fluentu.com, it is like YouTube but with better subtitles and a dictionary For TV: Try kids cartoons first if you find American sitcoms difficult!
