I am Speechless...
For every place, there is something worth the coming. Those are my words when reviewing this show. You my friend, have crossed the barrier between Sprite Animation and Full Entertainment. You are not simply one of the million flash artists out there, you are an artist. I can honestly say, that if it was not for Super Mario Bros Z, I would not even come to Newgrounds.
I have been following the show since you first posted the intro, and I must say, watching this episode is probably the highlight of this day for me. Being a big DBZ fan, I can see where you got a lot of the ideas (IE the yoshis being like the Nameks, getting their "planet" destroyed, and having to find a new one). I have not seen something so action packed that has made me want to cheer for the heroes since well.... DBZ
Leaving my coherent personality aside, here comes the fanboy for SMBZ. First off, Yoshi is a fucking badass HANDSDOWN. The Mario and luigi tag team is inctrdibily well done, and I cannot wait to see a good Sonic/Shadow one or Mario/Shadow one [besides the one against the koopa bros].
In my opinion, one thing in the later episodes that can make this show even better, it's if a main character dies, and in his deathbed, he offers to give all his powers to another character [like for example, luigi to mario, or shadow to sonic, or even sonic to mario].
I can honestly say, I will be checking daily Newgrounds just to see when episode 7 will be on, and when it does come on, you bet your ass I will praise it like Buddah ;).
