Thread: Good British serial/sitcoms/movies

For some reason, I understand spoken American English much better than spoken British English. While I have next to no problems watching American movies or serials (well, except when someone speaks with a broad South Carolina accent ), I find watching British movies rather stressful: it is harder for me to understand what is being said. So I decided to obtain some British serials or movies and watch them for practice. I would be happy to get some suggestions.

My requirements are rather simple: it must be entertaining in some way, either funny or intriguing or full of suspense (like a crime story). Sci-fi is fine, too. As long as it is not dull, it is ok. Among the things that I do NOT like are chick-flicks and most soaps. A.L.F. is an example of an US sitcom that I rather enjoyed, especially the first season.

Oh, and, of course, the cast must be mostly British. A British production about adventures of an American in Germany would be no good for my purpose

So, guys and girls, what can you suggest?

I haven't read all of the comments but you mentioned you love suspense and sci-fi and to see a wonderful sci-fi and a great variation of British English dialects I suggest Doctor Who! Also Sherlock, Merlin are great English series too. If you're into teen drama Skins UK is one of the best. I personally haven't watched but there's the Office UK and Shameless UK as far as I know. Call the Midwife is half drama half comedy.
