The Dark Crystal.
 

Awesome 1982 fanasy epic from Jim Henson and Frank Oz, always adored this since 26 years ago when i was 3 and this movie became one of my top 100 movies ever. Jim Henson and Oz with Brian Froud created a unique movie as this movie was the "Avatar" of the 80's of creating a lush world and original creatures. Brilliant puppetry, realistic creatures, a magical score and darkness abound makes this a must see.

Unfortunately another Jim Henson movie came along called "Labryinth" came 5 years later and stole some of this masterpiece's limelight as it's more popular than TDC which is unfair and has a bigger fanbase. I still think The Dark Crystal is a better movie.
