Ok so I can understand how you can say “I don’t like suchnsuch character in suchnsuch movie”, especially if you haven’t read the books or comics or aren’t familiar with the ancient mythology or whatever extra source material there may be. Movies don’t and can’t include all of the depth a character is intended to have, and often the director’s vision is different than the original writer’s.
But I feel incredibly saddened by the person I just met who bases his entire opinion of Marvel on one Spiderman movie.
