I watched this back in 2001 and enjoyed the series. I have not seen all of the episodes but I've made a point to do so this year. The pilot sets the stage for a series that is just fun to watch and relax to. To me, all the actors except Tom Welling are great (and TW seems to become a better actor as the show progresses). I'm still shocked at how Allison Mack's life went; however, for nostalgia as well as entertainment, this show is great.
The pilot introduces the FOTW. If you have to ask, that is the 'Freak of the Week' that dominated the earlier episodes. A character would be affected by the meteor rocks (Kryptonite) and do something that young Clark would have to take care of using his secret powers and despite the effect the meteor rocks have on him.
It is also fun to look for 'Superman' references as well as other interesting 'easter egg' type things in the show. Lana's 'man or Superman' comment is obvious, as is the 'S' on the scarecrow's chest. This time around I finally noticed that the 'Welcome to Smallville' sign says 'Population 45,001'. 45,000 and '1'.
Overall, just fun to watch.
