To me already with 10 years remained a terrific movie and. While the "worst" film of LotR trilogy (2> 3> 1 (Frodo annoys me a little in the third part)), but still better than anything today is the cinema. Anybody who may Fantasy Fan calls and must not avoid these films. Oh come when in the years to see the effects, etc. also for today's standards still great and must be the same as computer generated characters / creatures not hide from Avatar, etc..
CONCLUSION: As a fantasy lover is the LOTR trilogy and the Hobbit duty = "you have to watch"
