Didn't see a "post your tl;dr opinion" thread yet, so here goes nothing,
Of all the sam & max episodes I found this one the weakest and shortest of them all (there I said it, you may shoot me for this). A lot of the puzzles were mind bogglingly bland and easy, the story felt like they'd chosen nostalgia over coherent storytelling, and most puzzles could have been so much more than "use a couple of these dialogue options to solve all of this".
Most of the story events felt rushed and unpolished, like they were written just for the sake of putting as many (old) characters as possible in game.
Of course it had its good parts, a few very funny jokes, revealing the narrator as villain cracked me up, and the style of its ending was cliche but nicely done.. But I'm actually disappointed in this one,
