I actually like the rest of the cast and their dynamics. Niecy Nash distracts from the rest of the show; her acting is bad and over the top.

Think part of the problem is how the character is written especially, as there is no way a rookie agent would get away with her insubordination.

Many times, the lead is written to have a sudden "insight" to solve the crime whereas the rest of the crew is doing the real work. The lazy writing gets annoying fast.

I enjoy the performance of the actor who plays her father, but I don't know how you would keep him in the show while writing her out of the series.

The Rookie works because Nathan Fillion is believable and likeable, none of which applies to the lead of this spinoff.
