I've been a Woody fan since the '60s, so I guess I qualify as a member of his base, though I decline to speak for other than myself. I'm not sure Mr Ejiofor was the lead, as it was something of an ensemble cast, but his performance was not at all why I rate this as one of Woody's lesser efforts. The sometimes unbearably stilted dialogue, which contributed to almost none of the characters being likable, or really believable, was the leading culprit for me. Another was Will Ferrell. I may be the only such person on Earth, but I have never liked him in anything, ever. Don't know what it is about him, but, blech.
Hazelle Goodman was the first black performer with a prominent role in a Woody Allen film, the near-universally beloved Deconstructing Harry. Let's move on.
