I wasn't going to collect this line, but once I saw Vader, I had to have him. After that, I needed all of them. I'm caught up to Mace and Dooku (still looking for Leia and redux Vader).
That being said, I love all the new ones. I think Sidious is going to be my new favorite. Luke I like, even the "Jello" slashing of his lightsaber. Obi Wan is good too, but I wonder why they didn't put him in a more dramatic pose. The only reason I can think of is to counter the headstrong nature of Anakin's Unleashed.
I hope this line continues for awhile and I can't wait to see Han and Boba.
