ending?

He asked for the eggs, Charlie recognize Him, but to all Charlie's questions, Ug just respond, "Things change, Charlie". Ug killed the Brad Dourif character... I forgot his name...Ethan went for some remaining eggs and closed the troops in the lab with the other Critters. Then Ethan confronts Ug with the eggs, Fran knocks Ug out, then a Critter Appeared, Ethan took care of it, Ug wakes up, Charlie Killed Him. After that Charlie,Fran and Ethan got into the spaceship that Ug arrived, and they evacuate que station before it explodes. They Survive.

I personally think that a final installment for this franchise would have been good, with the Earth again of course, and I can imagine a way to introduce a fifth one, but as years go by I dont think a sequel would see the day of light. But there's also a cliffhanger between the 2nd and 3rd...

Hope I helped you out with the ending.
