Well, certain people feel strongly about certain things that you may not. For example, a lot of Tron fans did not go to see Tron: Ares the past week because of Jared Leto's involvement (over allegations that have been hanging over him for years). I agree it's silly to get worked up online over a film (people get worked up over much less on here and elsewhere), but people don't need to see so much as a clip if they decide not to go for their own reasons. I'm undecided yet. But I loathe biopics anyway.
