sequeltastic 

When the ending to a television show, book, or movie would work far too well into a sequel or followup of any sort, or the ending of the item is left open expressly for the purpose of a sequel.

The ending of Return of the Jedi was SEQUELTASTIC!

This is when something is really really cute, or makes you really excited.
Leaves you all giddy inside.

Have you seen the new get together date movie? It's squeetastic.
