It is the 38th animated special based on characters from the Charles M. Schulz comic strip Peanuts. It is one of two specials that have yet to air on TV (the other is It's the Pied Piper, Charlie Brown).
According to wikipedia, "It Was My Best Birthday Ever, Charlie Brown was one the final television specials completed during creator Charles M. Schulz's lifetime (along with the next special It's the Pied Piper, Charlie Brown). He died in 2000."
It is also unwatchable shit.
Seriously, this is jaw-droppingly bad. This is RIDICULOUSLY BAD! You will not believe how bad this is. Seriously! It is SHOCKINGLY hideous! It has the horrible quality of a badly graded student film hastily assembled and created quickly with an old, outdated apple laptop by a retarded six year old. THAT, my friends, is how bad this is!
No sound quality, repetitious scenes over and over again, bad script, horrible pixellated animation, a lousy script, absolutely hideous voice acting, and what seems like 45 straight hours of rollerblading.
This is the "Manos: The Hands of Fate" of Charlie Brown specials. I half expected Torgo to show up.
You HAVE to watch this:
What you have seen you can never UNsee!
