Movies making Harry seem weak?

[itzgoodnite]

  I'm disappointed that the movie's do not show more of what Harry is 
capable of. 
 In the SS/PS movie we have no idea that Harry can, without wand or 
magical knowledge, grow back his hair overnight or find himself on the 
school chimney when Dudley and his gang had been chasing him. 
  In the GOF movie Harry was not shown shaking off the imperious 
curse.  The movie also decided to show Cedric fight off Krum in the 
maze when indeed it was Harry who stupefied Krum.  Non book readers 
are missing out on the subtle hints that Harry is more than he seems.  
  Shouldn't more of these hints be included in the movies?
