Sure, it’s a sci fi movie for kids so it doesn’t have to be scientifically accurate, but the way they portray it is completely nonsensical. They show Buzz Lightyear trying to reach light speed in his space ship. Each time he flies around the sun, he goes faster, but more time has passed on the planet he left by the time he gets back. In reality, the faster you go, the less time it takes you to get somewhere (from some external reference of time). It’s just your experience of time that changes.
Interstellar is at least a little bit closer (ignoring the whole time travel part)
