The Passenger cemented the fan reaction to Bashir. From the start he came across as a genuine jackass; juvenile, awkward and (aside from his medical ethic) unprofessional. The Passenger just added another layer of loathing because...he...talks...so...slow as Vantika. It isn't until Past Tense that Bashir "grows up". After that, Siddig is superb, IMO. After such a rough start, Bashir became one of my favorite Trek characters.
