In Empire Strikes Back, we're told within hours of a presumed hyperspace jump by the Millennium Falcon (from the vicinity of the outer rim planet of Hoth) that it would be "on the other side of the galaxy by now". Yet other SW material show that the galaxy isn't entirely explored or occupied by the Empire/Republic. Keep in mind that Empire Strikes Back is considered one of the greatest films in the history of cinema, yet that stupidity you point out in ST5 is repeated line by line in ESB (worse even, other side of the galaxy is a good deal farther than center of the galaxy, and unlike ST5 where the timeframe of the journey isn't clear, it's clear that Vader's impatience meant Piett was giving that assessment within hours of the Falcon's presumed jump). I'm really thinking you guys' dislike of ST5 is having you be overly harsh of the travel time aspect in one movie and then letting it slide in another.
