It actually takes more talent to make a creatively successful un-ironic film than the other way around. Sentiment and sincerity are much more difficult to pull off than detached irony, above-it-all nihilism, and superior snark. To make sentiment and sincerity work, the audience has to care about the characters and the situation, they have to invest in every aspect of the story. This also, of course, involves a much richer and more satisfying experience for the audience.
