I thought it was terrible. There are very few actual jokes in the movie. Its "humor" comes from just making random references to Star Wars and other pop culture items.
"I'm going to quote a line from Star Wars in this instance, and that means it's COMEDY GOLD! Do you see what I did there? I took a line from Star Wars and said it in response to a situation! I'm funny! Do you not see how funny I am?"
Nail, head.
I saw this in the theater and I wanted so bad to like it, to find it hilarious, to think it was worth the wait... but it wasn't any of those. The Trek parody wasn't even clever, Terminal Cancer Kid didn't even give the slightest indication of having said terminal cancer... whatever. It was a huge disappointment and boiled down to what JKTim said above.
