I actually prefer the "Donner Cut" of superman 2 regardless of the re used ending. The intention was to always use the world spinning backwards for the 2nd movie.

I much prefer him getting rid of nukes into space causing the zone to crack and break rather than the entirely NEW PARIS intro with the terrorists they came up

I always hated the cheesy oops I tripped and feel and my glasses fell off, for losi finding out he was superman to the AWESOME and SMART way they did it for the donner cut.

there is no plastic wrap superman logo silliness in the donner cut lol

Luthor wasn't full familiar with all the crystals and the machine or how it worked so in that regard it wasn't exactly hard to use it to his advtantage since he had all kinds of time to prepare before they found his fortress lol
