I just watched the season six finale of Smallville and it ended in a cliffhanger as expected. And it’ll be back next season, also as expected. It was consistently one of the CW’s top-rated shows this season, so I figured it was very unlikely to suffer the same fate as Gilmore Girls. The seventh season should get underway late September or early October.
There’s a chance that Smallville may have an eight season, but that would be its last according to Executive Produce Al Gough:
We’ll officially find out about season 7 on May 17th [during the CW upfronts], but obviously we feel very confident we’ll be back. As for season 8, who knows? There are a lot of factors that will play into that decision, not the least of which is the quality of season 7, so that is what we are focusing on at the moment. If there is an 8th season, that would be the show’s last. Every hero may have a beginning, but every story has an end.
With that in mind, I hope they go the full eight seasons! It’s a nice round number (and lucky in Chinese culture). Would make for an excellent DVD set.
As for tonight’s finale, it was pretty intense. Perhaps not as good as last season’s finale, but still pretty good. I won’t give anything away here, so if you want to read some discussion regarding the episode, check out KryptonSite.
The one thing I will say is this: the Martian Manhunter was entirely underutilized. Such a waste.

It would be nice if after season 7 or 8 if they would make a new series continuing after clark as become superman.. I personnaly prefer the smallville story line compared with the superman movie story line..
A story might have an ending.. but no one said they could not have another one.. just a tought
was thinking the same, clark becoming superman,
is a very good idea for a sequel series,
I think it would be much better the the superman movie, or the Louis and Clark series
