Matt Brett on Viva Pinata:

Underneath the layers upon layers of cuteness is a ridiculously fun and addictive game. It’s super easy for youngsters to pick up with step-by-step walkthroughs for everything accompanied by full voice-over instructions. But it’s not [so simple that] someone like myself, who is normally shooting people’s faces off will tire of it in an instant.

There you go. Viva Pinata is good fun even for people who are more into the “shooting peoples’ faces off” genre of games.
