Watching Quantum Leap for the first time.
The difference in quality between "shot in the 80s" and "shot in the 50s" and "shot with 80s CGI" are very jarring.
It would be fun to do a series like this today but to match the quality of the old stock footage in the historic segments so it all feels more seamless and based in the correct time period.
Modern deepfake tech would also make the mirror scenes much less pathetically bad.
