It does remind me a bit of Jailbusters, but they differ in this way:
In RGB, the guys got lured into traps. The while story was kind of playful.
In this story, the guys are just yanked off of this plane of existence.
Egon is plucked straight out of the friendly confines of the firehouse, and Ray is grabbed proton gun in hand mid-stream.
Their whole world (and the next) suddenly feels incredibly unsafe. It's strangely shocking and ups the gravitas considerably. It's a really exciting development.
For some reason, when "the Other Side" tried something similarly menacing, it didn't quite work. I think the ongoing series has done such a good job getting the characters and the tone right that this threat seems entirely credible and that much more alarming.
… as an aside, perhaps the belt gizmo should actually have a function as a field generator to prevent spectral abductions from happening.
