First, SPOILER ALERT.
Watched a while back, but idk. I got bored halfway through the second season, it looked like it would stay in the "weekly villain" or something and the story was getting a little absurd, like his wife suddenly becoming a drugged crazy hoe, kidnapping his other love interest and bla bla bla. I don't remember much.
Another reason was because Bruce never seemed to become the teenage hero i was kinda hoping he would be. Especially because he discovers his iconic cave at the end of the first season. Cave which harbors some great secret from his father, which he can't unlock just yet. Seemed like a cheap cliffhanger to me, btw.
