Yes, spoilers are getting more and more difficult to avoid, but man, let me tell you, if you *can* avoid them as much as possible you will be floored when you're actually seeing it.
I've seen the last few big movies with minimal knowledge (ie. just looking at the official trailers, avoiding TV commercials and Internets as much as possible), which means I've been actively avoiding spoilers for like a year.
I AM LOVING IT
I've even gotten to the point of "unfollowing" friends that have a tendency to spoil things, even by accident.
Sure, there are many that want to know everything, and that's fine, but try your best to avoid stuff, I can confidently guarantee that you'll enjoy yourself more, even if you end up NOT liking it and losing $20, the risk vs reward is totally worth it.
Next up: Fantastic Four, then Hunger Games, then *drool* STAR WARS!!!!!!!
