Unfortunetly I can only give a 3/5. There were more things that I didn't like and think that should be improved.
What I liked: Positive to see Illinois keep presenting specializations on Coursera. The material was ok, with clean presentation style. The case studies is a very positive resource to have in the course to think critically.
What I didn't like: The course is excessivelly short, with only 30-40 minutes of videos per module. Previous courses in both specialization - digital marketing and improving videos have at least 1.5 to 3 hours of video materials. A huge gap. Also if I benchmark against the top specializations from Wharton and U. Michigan (Business Foundations, Business Analytics, Leading People and Teams and Finance: Valuation and Investing) all of them pack a 1.5 to 3 hours of video lectures. There is a huge gap. Also I didn't found the quizzes challeging. In a digital world content is king - both in quality and quantity. You have quality, but are missing the quantity. Unfortunetly I see a trend - the other course of the managerial economics specialization also is very short. A minor thing that I also didn't like was the form that the slides were presented. As in previous specializations - in my opinion all of the module slides should be in the readings section in only one document, instead of divided in small pieces per video lecture.
I hope that yu accept my critic as constructive because I have liked most of Illinois courses and was very impressed by the quality and extensive set of videos in the Improving Business speciaization.
