Like it but don't love it This show would be greatly improved if the stories weren't so simple-minded. The action, special effects, acting, and general idea are all very good. However, there are too many corny, insignificant characters that take up a great deal of the time. Also, the villains-of-the-week are usually ridiculous.
-----Mild Spoilers Ahead!!!!-----
Furthermore, considering that some monster arises and kills someone every week, wouldn't the nation be focused on Smallville after a while? I mean something needs to be done about a place that some kid begins eating people or something similar every single week.
But that's not even the low point of the show. It's usually when Clark's mom or dad tries to reason or make some decision. Clark's dad gives free cars back. Clark's mom couldn't figure out that this girl was changing shapes despite all the overwhelming evidence, although she tried very hard. Also, although the entire town had been talking about a bank robbery all day, Clark's mom didn't make any connection between the huge stacks of dollar bills that she found in this girl's house.
Worse than that, neither of them understand that Clark's could make millions upon millions in pro sports. All problems would be solved and he would be set for life. However, Clark's dad doesn't support him playing for the high school team because "someone may get hurt". In a town where cannabalistic mutants and fire-breathing coaches are found every week, football injuries are quite a big concern.
