It was more about the tech used to make it back then than the movie itself. The story wasn’t awful, but you’re right, it wasn’t that amazing, either. I think the only neat thought experiment that stuck out at the time was the idea of what consciousness meant/what is a soul, which not many mainstream movies discussed back then aside from the Matrix. Of course, Black Mirror did a far more phenomenal job of this idea with their San Junipero(sp?) episode, but that was almost 10 years later.
