I don't know whether Colm Meaney enjoyed playing it, when Miles O'Brien got shit on ... but he always delivered. I don't think O'Brien ever gave a dishonest performance, in his entire history with STAR TREK. I was always impressed with how solid his performances were. I wondered what kind of actor he was, I thought he was like one of the "method" actors, he had to be - surely. But no, he said his acting was much more "superficial" than that. Amazing.
