This time around we get to see some of the development process that went into all those technologies that make interstellar colonization possible.

The Bobs actually encounter problems they have a hard time solving.

The reliance on one time busters instead of lets say a drone with a Gatling gun or at least a number of guided missiles, seems like a contrived limitation. Especially considering what happens towards the end.

As before the Bobs are having fun and so am I.
