You should like my girlfriend, she got bored half way through, dropped Sopranos after 4 seasons because it was too slow, I think she lasted 1 season of The Wire that said I know what you mean, it's slow but I find it good none the less.
I got half way through the 2nd season of the wire before ditching it Sopranos, I can watch multiple times though
Only seen snippets of boardwalk, may have a look at it over the weekend
Me to, ive watched sopranos through end to end about 5 times. I just got back from New York yesterday, and while i was there I went on The Sopranos tour...! If you're a fan of the show it's well worth going... It was a 5 hour tour taking in the various locations from the series, finishing up with drinks at the Bada Bing where I had several tequilas with the bing girls...
...also sat in the booth at Holstens where the final scenes were filmed... It was great.
Me and Vito...:
Booth from final episode:
... As for boardwalk empire and the wire, I only managed the first 3 episodes of each, I too found it too slow!
