Oh, well. I still want to see it, though I'm thinking that they've pretty much beaten Mechagodzilla to death. The concept's been rehashed what? FIVE times in the series? Six, if you count MOGUERA from G vs. SG. OF the "Millennium" series, my only favorite thus far is GMK. I really just cannot warm up to the G2K suit.
I've got HUGE hopes for GFW.
This gives a very good synopsis of TOKYO SOS:

It does give the whole story away, so SPOILER ALERT! :) I agree also with its criticisms, including the fact that it felt "rushed."
