I just re-watched the Sopranos last month. My first few thoughts:
My god - this is how the rest of the world is going to think we sound. These accents are so over the top.
Then I realized... I probably know 30-40 people with that accent.
I re-watched it about 3-6 months ago or so. I think we finished it 3-4 months ago.
I watched it with my friend, who had never watched it before this.
Funny thing is that James Gandolfini was in fact from North Jersey, but he didn't have that accent, nor a particularly strong accent native to the area. He went to a voice coach for it. I'm not sure how many of the other characters did, if any of them.
In the pilot episode, there's two very noticeable differences with the character of Tony compared to episode 2. The first is that he's very noticeably slimmer. And the second is his accent isn't very strong yet and he sounds much different from episode 2. The first episode was actually filmed a whole year before episode 2 and the rest of the first series, because they made that to put it out there and see if it would get picked up, and they had to get it approved by HBO (or another network) before they went ahead with filming the rest of the season. They made him gain I think it was 50 or 60 pounds for the role of Tony, because I guess they wanted someone with significantly more weight/fat on them than what Gandolfini had when he was cast.
Tony is a bad guy, but he's a little more humanized (as much as he could be) then almost any of the other fellow mobsters, other than probably Bobby. One thing we both found funny is how Tony (and many others, like Phil and his wife/family) they hide behind their Catholic faith only when it's convenient for them. I don't think we see Tony in church once when it wasn't for a funeral. Which obviously Carmela attends because that's how she knows the creepy priest. Yet he has a problem with his homosexual co-worker (although clearly not as much as some of the others or Phil) because he's a ''Strict Catholic'' and he also doesn't believe in divorce because he's ''Old school'' and a Catholic. But his Catholic faith certainly doesn't come into play in his beliefs on adultery or stealing/murdering people.
