I'm admittedly not a huge fan of Segal, but I think this is an instance where he was obviously miscast. I never believed he was a junkie for a second.
All true. I never once got any sense of his relationship to the drug or the lifestyle. He'd just slap his hands together after he tied off like he was having a great ol' smacko' time, and I guess we were supposed to assume this is what being a junky looks like.
I'm generally ambivalent about Segal. I honestly don't think I've seen him in much at all.
