Smallville - anyone watch this and care to review?

[Wires]

I had passed on Buffy until season 6 when I finally picked up the show. It was great. I was able to watch 7 seasons of this fantastic series back to back. I did the same with Angel and was again able to enjoy all of the seasons consecutively.

It was a month or so ago that I realized Smallville had been on for seven seasons. It was a show I always had some interest in but never got around to watching. I just wrapped up season 2 and things are largely meh. It certainly isn't terrible and the potential is there for it to be very good but I'm not sure if it is currently good enough to invest another 4 seasons of my time.

Without any spoilers can anyone tell me if this show picks up in the next season or two or does it largely keep its monster of the week format? Is it worth hanging around for any reason other than the "LDO Kristen Kreuk is smoking hot" factor?
