I mostly liked the character— it was his singing that I couldn’t stand. His voice sounded like several tons of gravel slowly sliding out of the back of a dump truck onto asphalt, mangling some of the best crooner tunes, the originals which were sung with Sinatra’s silky smooth voice. I always skip past any time he sings— it’s unbearable.
He’s a fine actor, though. I really liked the episode with Nog and helping him with his PTSD. Some of the other writing was problematic, but not his fault.
