Breaking Bad! One of the best shows on TV for my opinion. You have to not mind the gritty stuff though.
Venture Bros - A funny show that makes fun of itself as much as it does other shows.
Entourage - A show about movie business which im sure has little to do but its a very entertaining show nonetheless
House - An entertaining show with an interesting lead actor
Viva la Bam - Really dumb but mind numbingly funny. As long as you like Jackass humor
Game of Thrones is awesome, I'm sure you'll love it especially since you liked Rome.
House MD - one of my personal favorites, medical drama (though you will likely laugh a lot too), first 3-4 seasons are very good, the others not so much, but still much better than most shows out there.
Dexter - another personal favorite, again, first 2-3 seasons are the best.
Bored to death - short, quirky, extremely funny, worth a watch.
I would highly recommend The Sopranos - throughout its 6 seasons, never once was there a noticeable dip in overall quality. The writing is fantastic - the various story lines which emerged over the course of the series were consistently entertaining, and personally, I've never come across a series where each and every character is so well-developed. So, if you're a fan of that whole crime genre, you're almost guaranteed to like the Sopranos.
I'd also recommend the U.S. version of "The Office" - Season 2 and 3 are the high points of the series, but everything up to and including season 7 (that's as far as I've watched - I just can't bring myself to watch the show post Steve Carell, considering how integral he was to overall mood and feel of the series) is worth a look.
If you are a total nerd Frozen planet and Unchained Reaction, if not Awake and Game of Thrones.
The HBO show OZ is pretty good, if brutal and graphic. It is set in a men's maximum security prison and has quite a bit of violence, drug use, foul language, male (and some female) nudity as well as a bit of rape.
And for another sitcom, Malcolm in the Middle. All seven seasons (minus one episode on season two) are available streaming from Netflix (only season one is available on disc).
If you've got about 60 hours free, watch Six Feet Under. Constantly brilliant all the way through.
Breaking In - its hilarious :P and almost just started Season 2 ^^
Thanks for reminding me! I completely forgot about it coming back.
These have already been mentioned by I can't recommend Justified and The Wire enough. They're both excellent shows that have the strong potential to bring father and son closer together.
