I think that since it was this decade+ passion project is why it's getting so much recognition. I thought it was a story about a kid's maybe-typical life, but not a terribly entertaining "coming of age story", because there wasn't much of a tale worth telling. But it was lovely enough and worth a watch.
*shrug* In the long run the only thing the movie give me was a bigger appreciation of the Harry Potter films. Besides, I can't really care about Boyhood that much when last year we had a decent chunk of really cool movies.
That said, I haven't got the chance to see Nightcrawler and Whiplash yet.
