Aside from the hardcore fans that will buy both the Kai and DBZ boxsets, I like many other people are conflicted on what to buy.
On one hand the DBZ Dragonbox's are the ultimate release of the series. Yet at the same time, all of DBZ's bad pacing issues, bad fillers, and drawn out episodes hamper it.
Then we have Kai. It fixes all of DBZ's pacing problems, gets rid of (most) of the filler, and will likely have a better dub to boot. Yet the negatives is it removes the blood, (Goku's death during Radditz looks awful in Kai), the Japanese soundtrack isn't as good as Z, and since it removes the training filler, you miss seeing the good guys actually train and get stronger.
I am conflicted, and I am not a hardcore enough fan to want to buy both. Do I get Kai, or do I get DBZ? What are YOU going to do?
