Oh my Maeggaladiel !!!
I don't think the Harry Potter fans liked that too much. you probably had to run out of the theatre and hide when the movie was finished.
Though I must admit I was actually thinking of LOTR as well when I watched the movie. Luckily I was able to keep it to myself. For example I thought Gandalf was a worthier wizard than the new Dumbledore. (Why did the other guy have to die

)
They even considered Ian Mckellen playing the new Dumbledore but then he would have been to Gandalfy especially for us LOTR fans. We would pick out the differences immediatly. But I'm rambling now so I guess I should stop.
