Okay, I've watched ROTS. Overall, it was definitely better than AOTC, but I'm unsure about where I would place it compared to TPM. They're both fundamentally flawed movies, but in different ways, which makes them a bit difficult to directly compare.

Anway, on to what I actually liked:

The opening space battle. This was nicely done, and I think it's about the only scene in the whole PT with Hayden Christensen that isn't terribly annoying. Unfortunately, it takes a turn for the worse once we meet the droids, but I digress...

Ewan McGregor. Like in AOTC, he's doing great here. I like the scenes where he's tracking down General Grievous (not the actual fight), and his reaction to Anakin's turn is very emotional and seemingly genuine.

Palpatine's seduction of Anakin. He has this down to an art form, knowing exactly how to appeal to Anakin's jackassery. Ian McDiarmid deserves a lot of credit here.

The scene with Anakin and Padme looking across Coruscant. Very emotional (something sorely lacking throughout most of the PT), and not forced like some of the stuff that comes later.

The transition to OT-style designs. Okay, it was rather rushed, but it was still pretty cool to see.

The soundtrack. I didn't praise this for AOTC because it seemed rushed in that movie, but John Williams is great again here, with music nicely fitting the scenes being shown. Very emotional.

The closing scenes. The last shot itself was a nice throwback to ANH, and the scene with Vader and the Emperor watching over the Death Star was nicely juxtaposed with this.

In conclusion.... I badly need to watch the OUT (thanks Harmy!) to get the memories of these crappy movies out of my head :)
