JEPD is widely discussed, though widely accepted depends on the academic circles. Biblical studies is unusually plagued by myopic assessments of where current scholarship is at, even failing to recognize the existence of alternative scholarship (this goes for theologically liberal and conservative camps). Either everyone has too much theological/philosophical skin in the game to concede legitimate, well researched, and opposing theories exist, or it Biblical Studies is driven more by worldview than research. On the JEPD theory, though, Umberto Cassuto's scholarship presented significant challenges to the JEDP theory as early as the first half of the 20th century. Continued scholarship suggests Wellhausen's theory was based on incomplete assumptions on the evolution of language common to his time (the late 19th century). The 20th century produced vast amounts of philological research unavailable in Wellhausen's time (late 19th century). More recently, John Sailhamer has done some very interesting research into the Torah (Pentateuch). His research suggests the seeming fragmented inclusions are not the result of numerous authors, but a single author using existing sources to weave a single narrative, similar to the Gospel of Luke. His incorporation of both Higher Criticism, Canonical Criticism, and liteary research manage to harmonize compelling elements from the various competing theories. Would highly recommend his recent(ish) book, "the Meaning of the Pentateuch".
