You’re lucky. I stuck it out and the ninth season had the requisite illegal alien episode (the guy hiring them was murdering them and Clark x-rayed a field full of skeletons) and the tenth was anti-military, anti-Christian, with an evil conservative talk show host version of New God character Glorious Godfrey. That tenth season soured me on the whole series and I never want to see it again.
That show about illegal aliens must have been in the 6th season.
It was really, really obnoxious. Simply an hour long commercial supporting their invasion.
There were some hot girls in it. Seems like the 7th season had less of Kristin Kreuk tho I am not sure.
