That minor tuned music is weird at first glance.. hearing, but it is actually pretty good.
The ending complemented it all.
There is no end to Mario's misery! No limit to "what SMB would be like in Hell".
This reminds me, I wonder if anyone has ever drawn a comic strip showing Mario's _real_ reactions to when Princess says "Thank you Mario! Your quest is over. We present you a new quest" after Mario saves her.
Mario would go, utter disbelief on his face, "O_o but I just saved you... were you just playing all along"? And Koopa would come back brushing off the fake lava from his shell and laugh merrily with Princess and Princess would explain "but you love so much those platform puzzles, we're doing this all for you!" And Mario would be completely wrecked realizing that while he has worked hard risking his life on multiple occasions, Princess was actually in no danger of any kind at all.
The new GB Smurfs submission reminded me of a movie I watched a while ago: Donnie Darko. In this movie, there's a scene where he and his friends discuss the smurfs way of life. It does talk about sexuality, so if you don't want to hear it, then don't watch it.
