Take the powerboat level for example...don't know if you've been there yet but it must have gone on for about 40 minutes, and not through mega landscapes but barren wasteland etc. It got to a point where I thought I'd maybe took a wrong turn as it just seemed to be going on forever!
The only time you stopped the boat was to do a simple task like open a gate or summut.
Don't get me wrong...its clearly a very good game with real cutting edge features...but I can't help but feel a little disapointed...I guess after all of the hype...it was going to be very difficult to make everyone happy (now where have I heard that before 'he says looking at a piccy of the 999')
