Yeah agreed. I'm sure I read once that the creator wanted it to end after the Freeza saga, but was pressured to continue. It felt like after the Freeza saga it was just repeating the same shit over and over again. Powerful bad guy, good guys not strong enough, train/evolve to beat the bad guy, people die, bad guy is defeated, dead people are brought back to life back the dragon balls... rinse/repeat. It really should have ended after the Freeza saga. Possibly even with Goku sacrificing his life there and actually dying.
