I was fine with Bombadil being excluded, just because having him in there would have completely ruined the flow of the movie, and to do it justice it probably would have added about an additional hour on to the running time.
I also didn't mind the Scouring being gone, just because it too would have ruined flow. And besides most of the general public had a hard enough time with the exsisting ending, and how long it goes on to them (of course it's not long enough for me

)
Most of the changes were made for a reason, but I still dislike many of the changes in TTT. Most of the other changes I either enjoyed, or can simply stand.
