When I first heard they were doing a Tron sequel I was ... underwhelmed. Coincidentally, however, I just saw the Legacy trailer this afternoon and am definitely planning on seeing it. It looks very good, to say the least (especially the extended light cycle sequence I watched - outstanding!).
I'll pass on the shoes, though.
Pax,

PS
The real question is, how did the Avengers trailer look? I didn't get a chance to see it before the clip was pulled.
