I loved it! It's a so tender story's that I was smiling all the time while watching it.
I know the story it's already been done, nothing original, but the casting is amazing at it, they are so perfect that it seems new again. The story of the first love, everybody has been there too. Love the main actors, the support roles too. I don't remember very much the music, so I guess I didn't hate it neither. I think the last song was fine though.
Perhaps the only thing I didn't like so much it's the ending... Too fast to really get what's the meaning of it. Totally worth it!
