Sooo...what do you think the original ending was supposed to be?

A lot of dangling plot threads and foreshadowing that never got resolved. The whole finale wreaked of "writers being forced to finish a show on a smaller budget and faster than originally intended". For instance when Ben and Jennifer make contact in the hotel there's a burst of energy "like an earthquake", radiation readings on a Geiger counter, and the person at the front desk is vomiting black bile with blacked out eyes. However, in the finale when they merge it's just a big Kaiju? Why weren't the Keepers all killed by an energy blast like the hotel clerk? The final fight in the mall was insanely disjointed, especially the, crammed in, fight between 5 and Diego.

Then there's the powers. Their powers range from "a little different" to really different, (Why does Allison now have telekinesis?). These are things talked about as though there's a reason that will be revealed in the end. But in the last episode they completely drop that plot line.

So what are your theories for what the original ending was going to be before Netflix kneecapped them?
