IMHO the real problem is the repetition of the "three-quests" structure.
Classic (and good) adventure games use this structure to make gameplay non-linear: nothing wrong about that, but Telltale chose to produce episodic gaming!
Because of that, we've been playing this same structure over and over again since The Great Cow Race (Max even made fun of that in an episode of Sam & Max). I think W&G Ep1 was funny, but the puzzle design is starting to feel formulaic and might be considered a disappointment by Telltale veterans like us. Whoever discovers Telltale games for the first time with W&G won't have any problem.
I'm with Kevin in the Gameboomer interview. Time to shake things up a bit.
About the play time: I've beaten the game in 3h and I swear I didn't breeze through it. I took my time to explore the scenery and enjoy the wonderful graphics. It's easier and surely less beefy than Sam & Max Seasons.
P.S.: I played a review copy of W&G ep1, so I've just tried the demo... well, it's FULL OF SPOILERS!!! Come on, guys... keep the demo simpler next time around.
