I think the backlash from this song came from that magazine a few years ago that called it the worst song ever or something like that. That is when many really started hating on it. I think had it been done by an unknown band, it wouldn't get as much hate either, but because Starship was once Jefferson Airplane, loosely speaking, many take the "how did a band that good end up doing a song like this?" stance.
It's really not a bad song. Okay, the lyrics are pretty hokey, and the sound and production is buried in that 80's sound that annoys many, but the melodies are strong. I have to be in the right mood for it, pretty much when playing an 80's playlist on shuffle, but it's not a bad song.
