The motors were fine. It was advances in battery tech that made pure EVs viable. Really, hybrids should have been a thing a lot earlier. Series Hybrid tech has been moving trains, ships and industrial equipment for decades before the Prius(Parallel Hybrid) hit the market.







Alien and Aliens were different types of movies. Horror vs Action. That’s why Aliens works. It isn’t a rehash of the first.
T2 was similar to T1, but a change in dynamics like Aliens did. Sarah Connor was more in charge and knew what to do about Terminators by the sequel.
