Most terms of office are a mixed bag of some sort or another. From what I've read, Rahm's approval rating as mayor fell below 20%, so there was obviously some discontent. And his mayorship has not been scandal-free.
But the other thing about Rahm Emanuel is his strong ties to old party blood. He was in the Clinton and Obama administrations at high levels. We need new blood.

One thing that would be interesting is he has no love for Netanyahu - that could be a deal breaker or maker for some.
Yes, also he rejects AIPAC and supports a two-state solution. At least there's that.
I wish him luck, but I hope someone fresher comes along for the primaries.
