Magnum2G3, they are not saying that MF is "not good", they are just trying to see if people would think that it would be better if it was longer. You are right, if they wanted to really extend MF notibly, they would have to add TONS of track, and the price tag would definitely go up. In addition, they would have to scramble for space. I dont know that much about the physics standpoint myself, but extending the track after the island may also reduce the speed or something. As to whether more track would make the ride better, it all would depend on how the handled it. And as for the height issue, CP was going into uncharted territory by breaking the 300 ft barrier, I'd say that the combination of that fact with the fact that it seems like most people's favorite part was the first drop, it is perfect as it is right now (JW, when you go on it for the first time you'll see what I mean).
