I like PJ's movies, haven't seen Bakshi's but I hope to somewhere along the line. I have some complaints about PJ's movies, for sure. I understand having to leave some things out that were in the books, otherwise they would be way too long for most people to sit through, but for heaven's sake DON'T CHANGE WHAT IS THERE!!!
That being said, I did enjoy the movies as I saw them, despite the inconsistencies. My extended edition of the trilogy arrived today, so I'm looking forward to watching them. With what time I have available that will probably cover a few weeks, off and on.
IMO Frodo's failure or success is kind of up for grabs. True, the Ring overcame him at the Crack of Doom, but he got it farther than anyone else had managed, and could anyone else have brought it that far, and carried it for such a long time, and not given in? Dunno for sure, but I'm inclined to think no one else would have done better. Gandalf had said that Gollum still had a part to play in the whole matter, which he did since he was the one who (inadvertently) destroyed the Ring.
I loved reading the Scouring of the Shire, and thought that it should have been included, even if briefly, because it shows how much the hobbits themselves had changed and matured over that time period, and without it we are left with several loose ends. In the movies we don't really know what happened to Saruman, or Grima. That entire business seems sort of...unfinished.
