For me Shameless is definitely one of the best TV series ever. It's a comedy and drama in the same time with lots of dark black humor. I was under the impression when I saw the first episode.
It tells a story about Gallagher family. Very non-typical family. Dad's a drunk, Mom left family long time ago, the oldest daughter Fiona tries to hold the family together. The oldest son Philip is sex addict and alcoholic Middle son Ian is gay. Youngest daughter Debbie is stealing money from her UNICEF.Carl is a sociopath and the youngest Liam is black, but nobody know why :)
I like Shameless because it is very different from other American series. Its very funny and unique. I can highly recommend it!
