I think the length has really been the #1 complaint -- but it's far from the only problem.
I agree with Eric and Mike: as I wrote in my review, the Jack Black character was all wrong. Why does he get to speak the last line when it's HE who killed the beast?? I agree Eric, you make a great point: he should have been killed off by Kong, at least allow the ape the opportunity to get some measure of "Revenge" or payback for the wrongs that have occurred (like Grodin suffered in the '76 film).
The portrayal of Kong -- I agree there too. Mighty Joe Young was a more "likeable" character and the relationship between Ann and Kong was never portrayed in this manner in previous versions...
I've re-listened to JNH's score. Saying it's not bad is hardly a compliment. It's really NOT bad, but on the other hand, it sums up everything that's wrong with film music today: there aren't enough themes to go around, nothing to take away from it at all. It's serviceable. One expects more from a score like this.
At any rate, NARNIA has pulled away from it, and Kong will have to take a backseat (to the surprise of most) as the #2 film of the Christmas season.
I find their new advertising campaign, with the stoic narrator quoting all the great reviews it received (still can't fathom most of them), somewhat amusing...especially when he says "it made me feel like a kid again" in the most monotone voice-over possible
It's going to be profitable with international revenues, but it definitely -- no doubt -- did not become one of the all-time blockbusters they were hyping and, naturally, hoping for. Cutting the movie would have helped, but there were other issues Jackson needed to address before filming.
