I still haven't seen House 4x02, but...
I hate Jennifer Morrison's blonde hair. I know she's a natural blonde and all, but she's got brunette coloring, and when your coloring looks better with your dyed hair, you stick with your dyed hair (yes, Gillian Anderson, I'm also talking to you). She's such a pretty girl, but the blonde washes her out and makes her look completely generic, as well. Add to which the fact that lately it's been such a dull, flat style, and basically, I just hate it. Please, go back to the brown.
