OK, my first sentence will be a Joss Whedon-style line that I take full credit for creating: If these tiny sets within the set that I watch on my TV set are digipacks, than I applaud Fox for doing such a terrific job!
If you bought the individual seasons in the past, well....too bad! The studio was just being practical by duplicating the earlier box sets again for this full series combined release.
Why would you want them to make a newly designed series of menus and graphics, when the ones on the original sets were just fine? I have no problem with the different menus of each season. The same menu would get boring after awhile. The only drawback is that the 2nd season one takes too long to get to the episode menu, and there is no way to skip that.
