I'm not mad I'm just disappointed. 
I'm not mad I'm just disappointed that you're not mad. 
When you can't believe you paid for this 
When the curtains open and you realize the movie isn't what you expected 
Is this really happening?' 
Mad peeved and not impressed 
When your date takes you to a comedy instead of a drama 
Cough it up, I guess... 
Sitting through this movie is gonna be torture!' 
I should have seen this coming!' 
What did I get myself into?! 
When the trailer looked way better than the movie 
This isn't what I expected!' 
Was this really a good idea? 
Looks like I'm in trouble again!' 
When the movie isn't quite what you expected 
What have I done?! 
I should have just stayed home 
I'm starting to regret my choices!' 
Here we go again... 
Just my luck' 
What have I done to deserve this? 
When you ask for popcorn and get a headdress instead 
When you realize you've been had 
Just another day of disappointment 
Oh great, the movie I wanted to see sold out 
When you see the dress code for the movie theatre
