I agree with most things you've said about Heath's films, Mikaela.
And I definiteively agree about 
Monster's Ball. I made it through the movie once (and barely so), and the next time I only watched it as long as Heath was in it. 
Also 
The Four Feathers; what a boring, boring movie  

I actually liked 
Brothers Grimm. It was a bit confusing, but I didn't find it noisy. And you're right about Heath's chartacter, very cute and endearing.
Apart from BBM, 
Candy is the Heath movie I like best. Great actors, griping story.
Ned Kelly: too much beard, too few eye candy
10 Thnigs I hate about you and 
A Knight's Tale: nice, entertaining, but that's it.
The Patriot: overly patriotic Mel Gibson flick with a very, very young Heath (not my cup of tea) and additionally his character dies. Enough reasons to not like it.
