In my opinion, visual effects are great when it compliments a good story, and action is great when it compliments a good story, but just to have them for the sake of having them, it gets a little boring, especially if you're talking a TV series. At least with a movie that's an hour and a half to two hours, you see it and you're impressed, and then you're out. With a series, if it's only that, week after week after week, there's nothing there to bring you back. You have to get invested in the characters and care about them and want to follow them.
