BEDA 4/4: Hunger Games Casting- Peeta and Gale

Okay, guys. So, today it was announced who would be playing Peeta and Gale in the Hunger Games movie. Josh Hutcherson, the boy from Bridge to Terabithia, is playing Peeta and Liam Hemsworth, the love interest from The Last Song, is playing Gale. I'm pretty disappointed that Hunter Parrish will not be playing Gale, but I guess Josh will be an alright Peeta. With blonde hair he looks a bit younger, and he's got a sweet face, and he's a good actor, from what I remember. I saw some of The Last Song, but don't remember much of Liam's acting skills; however, he looks NOTHING like Gale. Gale is supposed to be 18. Liam is 19, but he looks about 30. And he just doesn't fit the dark, mysterious, handsome, tough-but-kind Gale that I had in my head.
While I'm disappointed that the actors don't really fit my pictures of the characters, if they're good actors, I'll be okay with it. I'd rather have really good actors who don't fit my idea of the characters as much than actors who fit perfectly but can't act. I don't want a repeat of Twilight- two leads who fit the description but give an emotionless performance.
And I'm also really worried that the movie won't live up to the books. Of course, it won't be as good, because the movies never are. But I'm just really hoping they don't ruin it.
For example, I love the Harry Potter movies. While I did read the books before I saw the movies, I still was able to love and appreciate the movies because they were so well done. Holes was another book I loved, and when the movie came out, I was really pleased with it. It wasn't exactly like the book, but I really loved the way they did the movie, and they didn't change it so much that it was completely wrong.
However, when Ella Enchanted, one of my favorite books as a child, was turned into a movie, it was so different from the books. Everything I loved about the book had been taken away and turned into something different, and it was terrible. I'm just worried that this will happen again with Hunger Games, because of how intense the books are and how difficult it's going to be to portray that on film.
Anyways, I guess I'll have to wait and see. I hear Suzanne Collins is writing the screenplay, and I trust her to keep it similar enough to the books.
Anyone else have any opinions on the cast?

I should go, since I have four minutes until midnight.
