A lot of people are saying the family appeal of the games, along with a triple A movie budget, may make Angry Birds the most successful video game movie and likely the biggest movie of 2016.
But I have also heard that this movie was overproduced, and that you'd have to create a very odd movie nowhere near the games concept for a film to even be possible turning people away.
I personally think it will do well, because Angry Birds just seems to still be selling and not just gamewise, but merchandise as well. I do agree though they put a big budget on the film however, that could make or break it. But I thinking even if they don't make back the movies budget alone, it likely would still not be far off, and merchandise sales would cover the rest.
