Because it's not an action movie? It is literally some dwarf with hairy feet going on a long walk?
Note: I have not seen LOTR, tried multiple times, it just bores the life out of me. The only decent thing I think, is those dudes who all look like the grim reaper and ride horses about, but I bet they come to some shitty end, such as a hobbit punching them in the cnut and then they die.
