Contains Spoilers but mostly a lot of fun.
When the seaguls start to sing the Theme Song
Watching the food battle scene
The Movie Plot
Plankton getting more screen time than Patrick
To every single joke
When we get into spongebob's brain
Each time I spot a nice reference in the movie (Shining, Mad Max...)
Only the last 20 min are in 3D
When I finally found out that the pirate was played by Antonio Banderas
When I realize the first episode of SpongeBob aired 16 years ago
Let's be honest, it was good, but the 2004 movie was way better, right?
