The upcoming remake has prompted some channels to start showing the old one. My dad's always been a big fan of it and wanted to get me to watch, but from the first or second episode the ultra-obvious Nazi metaphor was so in-your-face it seems to insult the viewer's intelligence...right off the bat you know the aliens are evil and have a pretty good idea what to expect, and there are few surprises. That totally ruined the old series for me. So you figure in the new series they'd address this huge obvious flaw.

Oh, wait, no, it looks like they've just done a little find-and-replace:
Nazis --> Democrats
Orange suits --> Gray suits
80s special effects --> Present-day special effects
Wow, way to class it up. Cash in on US political divisiveness.
