there's nothing wrong with a little competition

I remember watching this movie when I was younger, maybe 7 or 8 years old. FYI, to clue up the people who haven't seen it:
'As the clumsiest, most clueless cadet to enter George Washington Military Academy, Kelly seems to be fighting an uphill battle to fit in. But it's all out-out war when she butts heads with Cadet Captain Stone, a tough-as-nails, by-the-book "commanding officer" determined to break her spirit.'
STAAAARRRINGGGG HILARY DUFF!

No. Just no. I think her acting skills were less than satisfactory in this movie.

But I can't say that for miss Christy Carlson Romano (25 years). She's possibly known best for her roles in the sitcom Even Stevens. She is also the voice of Kim Possible in the animated TV series.

Conclusion: Christy showed up Hilary in this movie. Fullstop.
