How much Frodo grew...

[The Only Real Estel]

In my opinion,movie-Frodo did only grow in one way....he grew into the weakest and wimpest character of all. Everytime something happened he went unconscious or 'couldn't take it anymore'

Sounds more to me like you're describing the side-affects of carrying the Ring farther & farther into Mordor instead of casting it away & sprinting for home like a weak, wimpy character would do who couldn't take it anymore.

I don't think that Frodo came across as growing a whole lot, you can attribute that to PJ or Wood or Phillipa or Fran, whoever you want, but Frodo seemed to grow stronger only minimully. The character who really growed in the movies was Sam, but that not particularily on topic .

He grew precisely 2.3 cm.
