I have written enough about the saddening story handling of Foundation already, but anyway... It is unbelievable the writers seemingly haven't even consulted anyone with any science or engineering knowhow. The scale of everything is a mess. Like, we gotta travel 50000 ly without a jump drive. Luckily our thrusters appear to be pretty amazing as the ETA is just a couple of decades... And wow, look at that planet in the neighbouring star system, the gardens, oceans and whatever seem awesome through this little telescope! But wait a minute, what the hell is that up in the sky visible to my naked eye? Darn, it is a hostile starship from another neighboring star system. Luckily they are still 48 hours away until they get here.
Seriously. Asimov was an actual scientist himself, these writers seem totally uneducated instead.
