Nothing on that list is intrinsically bad. All of them actually rank up in terms of movies I would sit down and watch time after time. There's not a more terrible one in the bunch. some have problems or I've seen them a million times, but all of them are fantastic films.
x-men was one of the few I liked! strange results...batman (especially that one got high rates)and spiderman are very populair (and x-men too), so why so many votes on those two? It almost looks like people read the title wrong, or you (the creator of this poll), changed the title. Weird.
