I don't want to sound overly critical of something I haven't actually seen yet, but going by the posted images I would suggest increasing the contrast a little and make adjustments to brightness to help things stand out / stand a part a little better...a lot of the scenes in general look a tad on the dark side and fairly grey.

In the posted shot of Obiwan [TPM] his face appears very dark and without colour information, slightly hard to make out. I'm sure it probably is easier on the eyes in motion though...

Also i'd think that using the title '30's serial edition' within the actual film itself kind of breaks the fourth wall a little.

The text cards do look a bit on the plain side, I'd expect them to be a little more fancy, Otherwise there doesn't really seem much reason to use those as oposed to simple subtitles. Maybe you could add something like imperial and rebel [or whatever era...] emblems in oposing corners?

And maybe make the text a bit larger since you have almost the entire screen to use. I do like the 'star wars' borders.

I AM still planning to check this out as I think it's a very interesting idea.
