I see why you are upset with this event. Compared to the Halloween Labyrinth (Belisha) or the Little Ghost Event (Alfie & Family), the events this year are a total buzzkill. I'm rather upset too. No interesting storyline or anything, just run SM and AFK for 30 minutes.
Fishing With Larry is AFK and yes, so is the lantern event. Sure you hunt monsters for the kits but then once you get a bunch, you afk by the lighthouse to release lanterns. Though this is optional, but not like it matters because the drop rate for anything good is total crap anyway.
Not really an AFK event. The current AFK event we have going on is Larry's Swimming with the Fishes event. This Halloween event only has you AFK for 30 min. to get 2 coins. In that period of time, you could be doing the daily SM's that award additional coins. Also, the Sky Lantern event is still going on, so even if you aren't fishing or you've already finished getting all the pumpkin coins for the day, you could be killing enemies to get sky lantern kits.
This past summer was also full of mostly non-AFK events too, and September was the only month where there was a lull in active events, and that was probably because people were going back to school. I respect that this is your opinion, but it has a very weak basis for an argument, considering the lack of actual AFK events we've been having recently.
