I was also v dissapointed with LOTR. The endless cgi was too complex, and went on far too long, big yawns. Frodo and Bilbo both ok, but Gandalf was miscast, and the rest just silly.
Most of the stuff was done in miniature and lots of extras. Only with the huge battles did they do CGI soldiers, and for special cases, like Gollum and the cave troll.
Honestly, what huge action movie doesn't have as much or (usually) more CGI? What did they use CGI for that they didn't have to?
Gadalf miscast... well I guess everyone's entitled to their opinion, your opinion just happens to be wrong.
If Sam and Frodo, or Merry and Pipin were gay, that's fine. It doesn't ruin the story for me, if anything it just adds another layer that it works on.
Saying the plot of LotR was "them walking for three movies" is like saying the plot of Zulu was them standing still for two hours.
The endings have been covered, and I feel no need to add to that.
