Cars is cute and clever. I like it. I'll post a review later, but:
X3: 7 / 10 (the SFX were good enough to bump it up from the 6 I'd give it for Magneto and Xavier both being complete dotards in this film). Compare this to the 8 I gave to X2 and the original X-Men. The franchise was so full of promise! Also, is Rogue ever going to do anything?
Cars: 8.5 / 10, the last 1.5 for the positive messages about humility, generosity, respect and good sportsmanship. The graphics are up to Pixar standards - 'nuff said.
