This is the show that just keeps on getting better:) Overall Shameless is just so easy to kick back, enjoy and get 2 invested for your own good. You learn to love the strange dynamic that the characters hold and feel like you're part of the family, whether that's a good thing or not.
Yes shameless is a train wreak... but isn't that the point? They keep it raw and real with a lot (not everything is realistic now, don't get me wrong) of what happens, and I think that everyone can find something they can relate to even if they hate this show nobody can stop watching it.
