TMOV Cop Out Ending?

The Merchant of Venice's ending could be considered a "cop out" ending or a strategic ending. The cop out ending being that Shakespeare just did not know where to take the play, so he ended it. The strategic ending being that Shakespeare did not want to write anymore because he had started to ramble and the play needed to end. I feel that the ending of this play was a mix the "cop out" ending and the strategic ending. The play ended abruptly and almost randomly because Portia and Nerissa appeared madder than they were and they just accepted the men's excuses. But could also be considered strategic because the play was coming to a close and needed an ending. I think that Shakespeare needed to either expand on the ring scene or end after the court scene.
