Honestly, the first time I watch Holidaze, I resented it. I found it very confusing, really rushed and just plain weird to be a Grey's Anatomy episode. But then I watched it again, and you realize something's very interesting about it.
It is a really solid episode. It's sort of like a transition episode leading to so many new interesting storylines (Little Sloan, Teddy/Owen/Cristina triangle, Chief's drinking problems) and much more.
Loved the Bailey scenes with her dad. Very strong. What a powerful scene it was for her to yell at her dad like that on Christmas dinner. Beautiful performance by Chandra Wilson. She needs a freakin' Emmy already.
Surprisingly, I didn't find Owen annoying in this episode. And the scene with him and Teddy alone in that closet as they yell at each other and she tells him she's always been in love with him...very powerful. And how Owen says, "I'm in love with Cristina." Freaking awesome.
The music in this episode was different than what we usually find on this show. It's quieter, more peaceful, and there's a sentiment behind every song. Great episode overall.
