In my oppinion the buncha frames series isn't as good as your other movies.
Some of the jokes are good but some of them arn't like the muchroom one. I don't know if it was just me or if i really just didn't get it hehe. Barely chuckled on the pirate and hat joke either.
I really enjoyed the I declared, Lumberjack, Unicorn and Restaurante* ones though ^^
The intro / outro is Just plain awesome.
And the music is of course a 5/5
Part 1 would get 3.9 / 5 imo.

A quickie of part 2 that isn't on NG atm.
in part 2 my least favorites was the exorcism, the dolphin and the mummy one.
While the rest was really really great.
Music is still a 5/5 and a slightly upgraded intro with the added characters.
I guess part 2 would get 4.2 / 5 :)
