The LotR films may have missed out and edited a lot of information (Haldir never died...he never even went to fight... - sorry, had to include that...my Haldir-fangirl-friend is standing behind me) but they were still amazing films...
If you take a lot of films in their context rather than their actual likeness to a book, they're usually actually quite good - apart from the Harry Potter films...don't get me started on those.
Mind you, I'm still a book person...I much prefer them to films!
