I've never really looked up to Hollywood as the benchmark of masterful filmmaking. Capitalist filmmaking, yes. Filmmaking as an art? Not exactly. Most Hollywood filmmakers look at cinema as a piggy bank, not as an art medium.
On the same note, I never really took the Oscars® seriously, it's mostly just a popularity contest. Oscar® — the tiny, golden, (and probably) naked guy — mostly favors the popular and the money maker, not the artistic. Just think: Hitchcock never won an Oscar.
With (alleged) propaganda film American Sniper getting lots of publicity and attention, it wouldn't be a surprise if the film wins the major awards at this year's Oscars.
