"The project topic itself is interesting, but longer (structured as 7 weeks); not much guidance until you find the right threads from mentors in the discussion forum from a few years ago or repeatedly google stackoverflow; it is much more technical than the rest of the course; and doesn't really use much of what was learned during the meat of the specialization's statistics/regression/ML courses, other than data science principles and tools (though new R libraries were needed).  These issues aside, the project was an interesting challenge to complete nonetheless.  Overall this specialization is now a few years old, and the plethora of 4 and 5 star reviews across all courses seem generous and out-dated.  Materials are not being updated, forums are a mess of years-old threads with not much current activity; there is a feeling of waning interest and participation. This was clearly cutting edge material and course back in 2014-6, if JH/Coursera intend to continue offering it, the material needs some refresh and reordering, tougher grading rubrics (I saw a lot of inconsistency and poor quality which met the rubric criteria, alongside great quality work), and more active involvement from lecturers and mentors (and, please fix the typos)."
