Why does FITB drop after MBFI acquisition?

New to investing here. Why did FITB go down so much after MBFI? I understand that the fundamental reason is that market believes that the acquisition was not worth the price they paid, but are there any specific reasons why? And more importantly, is it a good buy as of now?
