that and the all star cast and billions of awards it got. not to mention its a great movie

Edwin of course, its not the best triology in the history just because of that part, but u know, that part is the definition of epicness. Also the theme from the shire is awesome, and the isegard theme is also amazing, those trompets man, those trompets. pd: i dont know if they are trompets or some other trompet cousin, sorry, i dont know all the names of the instruments in english, sry about that. I do believe its a mixture of the bigger brothes of the trompet

besides LOTR what other trilogies would you recommend?

Edwin the godfather, pirates of the caribean, but the only really good ones are the third and the fourth, basicly the ones where johny deep is the main character, if you want some action, batman or spiderman, star wars, but only if you like sci fi, matrix, although i have only seen the first one, i can tell its a good begining for a triology, and thats basicly all i can recomend, only the godfather stands up to lord of the rings, the rest arent as good, but i mean, being worst than the best triology is normal XD

The Godfather and Pirates of the Caribean are amazing trilogies just like LOTR :)
