What do you mean by 'too many'?
A couple have been given high publicity here but when put into perspective as a proportion of how many uneventful flights happen in Airbus (or similar technology) world wide I can't see it as being a huge issue.
As a general comment on this whole thread, presented with a really lousy situation, this crew did a very good job and, no matter how many of us from our armchairs believe we could have done better, I doubt it really.
