I'm pretty new to the scene but have to say that 80s and 90s games have more draw than Stern's titles. They all seem to have a whimsical nature, be it Monster Bash with it's amusing call outs, or Addams Family's "Flip, Thing, Flip!" and the Bear kicks. The games have solid humor and are not too serious by any means.
I can't think of a modern Stern that I've played where the game has that element. Even a game like TSPP, based on a comedy cartoon, doesn't display the sense of humor that B/W had.
Of recent games, I think only Houdini has moved the needle back to that light-heartedness. Spooky may have made some strides here, but I haven't played too much on their games. Even Dialed In misses the tone I think.
