Well, I'm going to give it the old college try! I've decided to start where the problems are: X3. I'm going to cut out all the lameness and remove the unnecessary subplots, but I also want to add a few fun things to the mix...like this:

Note how in our first shot of the Sentinel in the Danger Room sequence, it has round eyes:

After Colossus and Wolverine perform the fastball special, the eyes have totally changed shape!:

Here's my first special effects change (this is just a test- I did it only to a single frame using Photoshop - it took less than 5 minutes):

Not only did I fix the eye shape, but I also brought back the Sentinel to its original comic coloring, without going overboard. In the final version, I'll make the eyes much smaller and fix their color inconsistency.

I'll keep you posted as other things develop!
