CAN SOMEONE EXPLAIN ELF TO ME?

I just don't get what's so great about it
  1. Why does every millennial love this movie?
  2. I have never not fallen asleep before the ending
  3. How does it even end?
  4. Is Zooey Deschanel even allowed to be blonde?
  5. Okay I'll give you that "Bye Buddy, hope you find your dad" is pretty funny
  6. But other than that, what's the deal?
