The first review is up for Sam & Max: Night of the Raving Dead at Eurogamer, so check it out. Unless of course like me you want to remain totally unspoiled. Only tomorrow for us non-GameTappers!
Update: There's also a nice spoiler-laden review over at CHUD.
And a spoiler-free review at Talking About Games, a site we of course check daily.
Adventure Gamers has also posted their review.
The Norwegian site gamer.no has also posted a rather positive review here. In Norwegian.
