Ok this characters that you used was seem before from Russian channel 2x2 and from nickelodeon at THT channel. this most famous characters are already made my world dream fantasy when I was kid, but this my world dream has been crushed since I moved in the united states so.... but also you forgot to add famous characters from The Simpsons, from Futurama, from American dad and from Family guy.
In 2x2 I watched many other cartoons like robot chicken ,The Flintstones
and other great cartoon commercials when I was kid but now this 2x2 is now trash channel [in my opinion] because there is no more 2x2 commercial page history and games in it. :(
In THT at nickelodeon I watched cartoons like Hey Arnold, My Life as a Teenage Robot, Catdog, The Wild Thornberrys, AAAHH!!! Real Monsters, and The angry beavers when I was kid.
But in Newgrounds unfortunately I have to say that all characters that you used as a crucial moments to watch was not your idea to use this cartoon characters anyway. Quality of drawing all that stuff was some drawings looked bad for me and some looked better but its like I can draw some stuff too in the paint brush.
Overall: This movie was boring to watch, so I will give you 2.5 stars.
