I didn't know there was a novel book. The movie kept me engaged until the plot holes started showing up at the end...
1. Time travel: Soichiro travelled to the past, did some work and was going for cold sleep again... then what about the one actually from the past going for cold sleep. Won't they both turn-up in future and the other one going on a loop and brining more Soichiro in the future?
2. Cold Sleep: Riko went to cold sleep 10 years after Soichiro, how come both of them woke up at the same time? Is she not supposed to wake 10 years after he wakes up?
3. Funding: How professor Toi knew that Soichiro funded his research and The Guardian CEO knows Soichiro from the past already (before it even happened)...? This proves that, one of Soichiro's version is running on a time loop... then in that case, there must be multiple Soichiro turning up in the future (2025).
The movie lags behind highly on time travel logic and concepts.
