^ Wow, I agree whole heartedly! Though I never expected it to be a show about Superman . I understand the no tights rule (though not necessarily the no flying rule since there are so many superheroes who can fly these days) and the revamping of classic Superman mythology. Let's face it, once you turn Mxpltzyk into a bookey, all respect for mythology has pretty much flown out the window, and yet I wanted it to be at least faithful to the core characteristics that make Superman what he is. He's brave, proud, compassionate, in a word, heroic.
Instead Clark is always scared, ashamed of his abilities, cares only about the people close to him, in a word.. angsty. 
Add to that an erratic development of characters (take Lana for instance), convoluting plot lines (like Veritas, which was good but contradicted most of the first 4 seasons) and you have a mess of a show that after 5 decent seasons, not only jumped the shark... it jumped the whole freakin primordial pool.
