While Gaim was a fantastic show, I want it to end. But I want it to end with a bang. Based on the descriptions of the final episode, it doesn't sound like it'll be like that.
And I know Drive may not be as good as Gaim, or maybe even better, but I think its important to focus on the good things a Tokusatsu series does. But if a show does too many bad things, and they overshadow the good, then you should give up on it.
