If you like comedy, maybe you can like a serie called The It Crowd.It’s about the daily life of two IT guys and one average woman working together on a company. One of them has a Irish accent, but most of the characters  have a  british accent.

When I watched it I laughed a lot.  It’s good to watch in those moments when you just want to relax and watch something funny. 

Hi Asem 

I'm watching Game of Thrones at the moment also and Arrow, i also watch The Flash which is the same team who produce Arrow. If you're looking for a British Series to watch Shameless, Skins and The Inbetweeners they'll teach you a lot of British slang. Luther is also a very good series it's a British crime drama. If you're looking for something to advance your English skills to the next level Sherlock is amazing. 

A few more mentions 'Top Gear' the car show program is hugely popular loads of series of that, If you're looking for an older British comedy 'Only Fools and Horses' is a classic and 'Steptoe and son' is quite funny. British television soaps Coronation Street is more traditional, Eastenders is more modern and Hollyoaks is based towards younger viewers. 

I recomend you  Peaky Blinders, it is about a Ganster Family, after firsT world war in England, the serie is from UK..
