Ugh, So many questions.
First of all I want to say, really really nice series so far.
Just a few things you should go over in your future episodes that I want to write about.
The first and most CRUCIAL thing that is needed in this series is better AUDIO, The stuff you use at the moment like the Japanese Dragonball Z Music and the Naruto stuff are really dull.. Try using some of the Original Music from "Bruce Faulconer", Then next time, I'll give your "Sound Score" more than a 2. *sigh* lol.
Secondly, Voice actors, See, I don't understand why you used Voice Acting in the first Episode, then the rest Subtitled. o.0
You really do need voice actors, Ask some of your friends, or post around in the forums. Then the series would be alot better. :)
Furthermore, What the heck is up with the Characters names?, Are you worried about Copyright or something? (Wtf), or are they like.. Son's and Daughters of Vegeta, Goku.. Etc.. etc..
Lastly, I noticed you used alot of scenes from the Cell saga in the Memory bit of Episode 6, And at one time you even used it from the Raditz Saga. o.0
Ugh.. All I have to say really now, Great job on the series so far, But try an improve on the stuff I've written above, then the series will rock. 8)
