No movie has been universally lauded. What makes your folks more trusted than Kanye?! Kanye y'all!
Some people might mark it down for the plot or character depth, but it very much is a movie of this genre. A tight "comic book/sci-fi" plot.
I think it's everything Guillermo set out to do and if people don't like it then they don't like it. It's not going to be a movie that divides people like Man of Steel did. The Man of Steel discussions ranged from the theme, plot, tone, to superman himself.
Here people will either get on board for the ride or it's just not their thing. I don't like sappy romance, so I won't hate anyone who isn't into this as long as they give it a fair shake.
If I were 13 I'd probably explode; it's very much for young people and teens as well.
