My brother has recently started watching MAD MEN and has fallen in love with the series. He is now on Season 2. He has been endlessly urging me to start watching this show -- so much so that he bought me Season One on Blu-ray. I started watching the first 4 episodes of Season One last night. I'm sort of lukewarm to the show at this point. The characters are rather interesting, but I haven't gotten to anything in particular that has "hooked" me into wanting to watch another episode as soon as possible (though I plan on at least finishing the first season). I know this show has been extremely popular over the years. Just wondering what I should expect in upcoming episodes/seasons that might make me a huge fan. Thanks in advance.
