Lt. Malcolm Reed was a cool enough guy. On the first few episodes of Enterprise he seemed shockingly intelligent. He liked stuff that went "'BOOM!'", which is good for a character in science fiction. And he was gay, then he wasn't, nor had he ever been.
Reed would have loved a 22nd century Star Trek timeframe that made sense, where space battles were fought mostly with nukes and ship-to-ship combat was brutal. Instead, this poor bastard was stuck on an anachronistic show that had no tension or drama to go alongside its combat scenes.
