Stuart's Exodus Commentary is a good example of the strengths and weaknesses of the NAC series as a whole. It's well studied, well written, and deeply evangelical in its outlook. The strengths of this are obvious for those who have similar leanings--Stuart will always seek the option that retains the most stringent positions on things like the good character of Moses, Mosaic authorship of difficult texts, etc., and defend it thoughtfully and well. But sometimes this apologetic leaning creates significant problems. For example, he bends over backwards to argue that "maybe the Midwives weren't _exactly_ lying" or "Maybe Moses wasn't a problem here," when the text provides simpler solutions in and of itself.
Furthermore, there are a number of times when his simple reading of the text at times lacks literary or theological depth because it's so focus on apologetic concerns. For example, Stuart is often so concerned at papering over distinctions in the text in the name of defending Mosaic authorship, that he misses opportunities to discuss what these tensions--which are present, even if not from non-Mosaic authorship--indicate, both literarily and theologically.
It's also uneven. The last half of the text is decidedly less beneficial than the first half! For that reason, it gets a 3*. Still, if you're looking for a solid, readable, well laid-out commentary on Exodus from an evangelical perspective to use in Church of Class preparation, this is pretty solid.
