Again: If you said "I like this specific comic book movie for being dumb," I would have no objection. But you essentially said "All comic book movies should be dumb," and that is insulting to a great many creators and fans. And if you don't care that you're insulting whole categories of people, that just makes it worse.
Going easy on the person, all that was needed was an IMO.
And regarding Life of Pi, they created a realistic tiger! Avengers was a great movie with great effects but I always love when effects artists make the real world insertions seamless and natural. Life of Pi deserved that award.
