I know I said I'd post this a while ago, but I was being lazy, so get off my back.
Season 3 contains some of the greatest moments in DBZ. However, it also contains some of the biggest time wastes in DBZ. I enjoy DBZ, but I am not fanatical about it. I think that is what makes these reprocessed and repackaged seasons so attractive to me. It is also my lack of fanaticism that made some of the episodes in season 3 unbearable. I honestly fell asleep watching this season on more than one occasion. The odd and ever changing hours I work is partly responsible, but also the fact that for five or six episodes in a row virtually nothing happens. I don't think I'm exaggerating when I say that there are numerous episodes that spend 25 minutes of the 30 minute episode rehashing what already happened or what is to come in "the next exciting episode of Dragon Ball Z!!!" I know that there was one whole episode that was entirely rehash. The WHOLE friggin' episode.
Now with the negatives out of the way, this season when good is GREAT. It sucks you in and takes you on an emotional roller-coaster. One moment you are on the verge of tears (or if you are less of a man you may shed a few), the next you are yelling at the tv, and the next you are cheering aloud in exaltation.
Season 4 starts out a bit lack-luster. This season begins with the Garlic Jr. saga, which I had not seen in completion until now. It was not DBZ's greatest moment. Although it does reveal some interesting character development, it seems very contrived and lacking the usual heart that DBZ has. Garlic Jr. is kind of dumb and he and is minions never really seem to be that big of a threat, even though they do almost destroy the world as we know it.
Once the Garlic Jr. saga is out of the way, though this season gets good, and I mean REALLY good. It starts out with some fun episodes that show the Z fighters in real life. Particularly Krillin and his hot, but dumb and self absorbed girl-friend Marin. When the intermission concludes and the action begins it gets and stays good.
When Trunks shows up out of the blue to face Freiza and King Cold...
This season focuses much more on the character of Vegeta, who is one of my favorite characters, than previous sesons. It also reveals the interesting characters of the Androids, who though evil, are much different from your typical villain bent on world domination. I am tempted to say that this is my favorite season to date, excluding Garlic Jr.
These things seem to be coming out about every 3 months or so. Let's just hope the next three months go by quickly.
