Ellie
Like everyone else I love the married life sequence but one thing bothers me a little.
We go from Carl and Ellie hanging out as kids straight to their wedding. In that transition Carl kind of looks the same, but Ellie looks a bit too different: She transforms from messy kid with bad hair and teeth into a sweet attractive young woman. There seems little similarity between them, you almost wonder if it's the same person.
It's only a small gripe.
