FlingSmash is good for some mindless, co-op fun for a while, but there are plenty of other games out there for that too. But if you want something that uses the wii mote that nearly anyone can play, it's worth at least a lazy afternoon. It's not really that FlingSmash isn't good or that isn't bad, just that it doesn't get interesting after the surface level of playing it, so really there is little reason to revisit.
