It would be nice to have a thread to discuss about DBS around here. Since no one created a thread for DBS yet, then here I come.
"Soooooooooooo, why the hell are you wasting your time watching this anime?! Just buy the 2 movies and move along!"
The answer is simple, it will continue with another saga after the ROF arc and DBS is adding much more details and changing a lot of stuff from the movies, making DBS a much more enjoyable anime to watch. For example:
Some good aspects of DBS: Fights scenes lasts longer than the movies, there are lots of space for jokes now, added more detail to the movies arcs, the violence level has been increased in the Frieza saga, a bit more detail to the Goku and Vegeta's training process; Goku is no longer the Nº1 on the earth, Vegeta is either at his same power level or he already surpassed him.
Some bad aspects of DBS: Lack of blood in the TV series (it might get added on the DvD version just like how they fixed the ep.5 sh*tty animations); some episodes features weird drawings, but not so serious like the ep.5; nonsense power scale (Frieza's power level goes from weaker than Super Saiyajin 1 to as strong as a Super Saiyajin God within only 4 months by spanking Tagoma and Tagoma goes from a Fodder to the "Imperfect Cell"'s power level only by getting tortured); Gohan.
As a former Gohan fanboy, I hated what they did with the boy at DBS, he is crappier than DBGT Gohan after ~2 years without training at the point of his body only being able to maintain SSJ1 for some minutes and being unable to acess his mystic powers. Akira Toriyama comfirmed the next Gohan design after the Frieza saga...
