You're right, I neglected Chiyo's revival of Gaara. I guess I personally make an exception for instances when people are only dead for a few minutes (call it the difference between "mostly dead" and "all dead" if you like). There are a few revivals like that, both in Naruto and elsewhere. All had positive portrayals, that I can remember. It's kind of hard, sometimes, to know when people are really dead, after all.
Orochimaru & Kabuto's Kuchiyose: Edo Tensei ("Impure World Resurrection") technique, on the other hand is more the kind of "resurrection" I had in mind.
