I'm well aware that it will never happen but I still wish they would tone it down with big (but boring) cameos, massive stages, expensive explosions, overproducing and overscripting every "trap" and running the great gags into the ground (drawer opening turning into multiple segment, etc.).
In the two onsen batsu games, Highschool, Police and Hospital showes it was all about Gaki members and interactions between them. That's all you need. Once the "new" formulatic nature and bigger production values became a norm, the Gaki members kinda stopped being the main entertainers and transformed into simple observers who're pretty much just sitting around, waiting for elaborately scripted cameo to happen.
It's probably much easier for Gaki members (and production team) this way, since there's no pressure on them to be constantly entertaining by themselves.
But still, to me, the best stuff always happens during the unscripted banter and truly improvised gags during their downtime in the main room, while they're waiting for another big scripted segment. (Sadly they're often interrupted by Fujiwara, who's coming to pick them up for the next transition.)
The two ancient Onsen batsu games were pretty much 100% just them sitting in a single room, relaxing and trapping each other. With Itao or other friends dropping by occasionally to shake things up a little. And it was pure comedy gold.
I realize why the big explosions and cameos need to happen now, but having 5 comedy geniuses with this much charisma, and comedic experience and wasting their time together on endless scripted bus rides instead of giving them some room for simple improv, feels like a damn waste if you ask me.
