Honestly, when you stop to look at the script for the evil endings, they are incredibly short. They're just very flashy.
I agree the epilogue could be better- but that the resources should be redirected to improving them now, not so much, despite my disappointment in some of the aspects. And I mean, if it was a fix the final battle and the docks vs fix the epilogue, I'd pick the first. The epilogue is fine, all in all.
