No, like I totally get that. I said that I get that. I agreed with you earlier. We are saying the same thing... A disjointed, structurally weak series of Hobbit films is something I hope we don't get, but I fear we are going to.
What I was trying to say is that the comparisons you drew to HP and SW don't work very well, imo. I don't think LotR or the Hobbit should be or can be anything like those in terms of plotting.
EDIT: By the way, about RotK... You did say what you thought was wrong with it, but how exactly would you change it? You complain about it feeling bloated, and then complain about lack of character development (which I agree with about Merry, Legolas, and Gimli but the latter two were given short straws throughout the whole trilogy). Whether you want to agknoledge it or not, these films were not about Aragorn, not even RotK. His plot line was sidelined because Sam and Frodo are the important ones. Now, they could have shifted the view away from Gandalf a bit and more towards Aragorn. I wouldn't have had a problem with that, except Gandalf's storyline is more interesting and better quality than Aragorn's (in RotK).
