For me -

• Teenage Mutant Ninja Turtles (1990)
• Godzilla (1954 & 1956)
• Gamera (1965)
• The Lord of the Rings (all three, extended editions)
• Crouching Tiger, Hidden Dragon (2000)

And proof that I'm kinda a film nerd (and I had family in journalism)...

• Citizen Kane (1941)

Oh, and most Star Trek movies.
