One thing I just thought of was I was never happy with the Bride that was blue and moved. (I think she was the one before the current projection one.) Her movements were too jerky. The best part about the Bride I remember as a kid was that her face was shadowy and mysterious and her eyes glowed.
See the bride pics
here. The top one is great, the bottom one not so much...
The whole cross-eyed thing bugs. It's someone putting up a neon sign saying, 'This is supposed to be funny!' That's not how comedy works.
Here are my fixes for it:
1. A projection on a 3D moving animatronic.
2. The bride whispers her lines, almost to the point that you can barely hear it.
3. One hand should carry a real bouquet, the other should be behind her back. As you pass, you see her gripping the axe behind her. If you see it, great. If not, great.
4. We should see a beating heart.
5. Her face should be shadowy and dark. No crisp image, no crossed eyes. In fact, her eyes should be looking downwards. As you pass, she could give a DoomBuggy or two a wide-eyed look. That would be creepy.
