I don`t think this album is so bad as often rated.
OK, I agree that there should be more technical thrash passages,quick tempos, and less slower groove parts that are used too frequently and not very original. But on the other hand, even if songwriting is not so strong, this record offers great musicianship (Steve DiGiorgio is one unique bass player, excellent as ever). Use of synths enriches the album too and sound is great in my opinion.
So this was no waste of time for me, good comeback album.
