The film didn't work for me. Slow paced and meandering, something the real Ali wasn't. Will Smith seems miscast and doesn't seem to capture Ali's unique style and charisma. The film suffers from a bad script and could easily be cut down by an hour. I hope someone does a new Ali story someday and avoids the mistakes in this one.
It had some great moments and performances but over all it didn't grab me as a monumental film it was hyped to be. The songs for me were not memorable. Not sure if I'd go out of my way to watch it again. Only time will tell.
