Its not *that* bad.
The main problem is that the motion controls can be really particular in the "cameo" game...where you have to mimic movements. You can quickly adjust and try different movements/angles etc... but wiimote newbies might get frustrated.
Otherwise its ok..but video game versions of board games are sort of limited and pointless at the best of times. Often the original board game is cheaper anyway.
80 bucks, noway... $35... maybe worth it.
