the two voyages
anybody who's watched all 4 seasons can see that there are really two VTTBOTS series.
The first which runs through season 1 and most of season 2, is a serious tense action thriller with a little bit of sci fi and fantasy.
From there on in it's just bonkers and makes no logical sense whatsoever.
I actually like the second better than the first even though they just make things up, like an implosion bomb, a nuclear explosion yards away from the seaview that never touches them, etc etc.
It's almost like the production team dropped acid halfway through season 2.
Pointless witty comment here ...
