The action sequences was what he had Riker for.
I admit Picard as a diplomat may not have been the most thrilling movie ever, but it would beat the loooooooong 'lets light the ship up from every imaginable angle' from TMP.
They should have kept him the diplomat and statesman that he was, commanding the ship through tactical combat in space, and leave Riker to handle the hands on fighting with the bad guy.
