Don't get me wrong... it's still a good episode, and I would recommend it, but it does seem to drop a bit in quality from "Boss Mabel". I liked Dipper's story, thought that Mabel's was pretty okay too, but I hardly got any enjoyment from Soos's. The concept seemed a little old (getting sucked into a video-game and whatnot) and there weren't any jokes that I laughed at.
The idea of the bottomless pit was creative, but I just thought the sudden storm while they're near the pit was just a little TOO inconvenient... I would of liked to see more originality in that department.
Overall, an above average Gravity Falls episode that's pretty good for a filler.
