This should've been titled "The Longest Flash Cartoon On Newgrounds". That's what it is! I hadn't seen any of these Christmas flashes before except "Santa Clogs". I thought it would feature some really old cartoons. Nope, it was almost entirely stuff that was made this year. My favorite was of course the Charlie Brown one.
See my review of that to see my thoughts on it. I also love that opening sequence. I thought the credits would be really long. Instead, it basically showed two more cartoons before ANOTHER credits sequence and one more brief segment of course. I've seen that National Lampoon poster. It looks like Snoopy!
Don't worry, I watched it so he won't die. Some of the segments were a little weak. I didn't care for "Billy And Willy". You should have advertised this as a feature length movie! Given some re-animated collabs, we easily have several feature length movies here! Merry Christmas now and for infinity!
