the CGI for stuff like the orcs was crappy.
I kind of agree (with her at least) on this point. It did seem like a huge CGI-fest. I'm willing to bet at least 50% of the film was completely CGI, and it would be more, but I don't want to say that 70% of it was CGI and then look stupid because I'm wrong and I don't really know what I'm talking about. Obviously they can't make real goblins and orcs appear without some level of computer trickery, but I still think they took the easy route a lot of the time with the CGI.
Also, on a side note, my 11 year old sister went to see it for her friends birthday.
She said "It was rubbish, it was all about elves and orcs. And there were so many fight scenes!!"
In my entire life I never wanted to punch someone harder...
