As with most of the commentaries in the Tyndale series, this one serves very well for my purpose, which is the preparation of a weekly Bible study class for an audience that is not -- and has no need to be -- deeply involved in the arcane minutiae and frequent wild leaps of logic associated with "serious" textual criticism.
The two epistles are well-set in their historical context, both in terms of the issues addressed and the order of their appearance among other New Testament works.
Linguistic analysis of the Greek text is competent and helpful without being overbearing. (I always study with two Greek texts open, but it is still nice to have somebody point out points of special significance.)
I strongly recommend this book for the purpose that I have described or simply for someone who wants to study the epistles to the Thessalonians with greater insight than that provided by many other commentaries but without having to wade through the "airs above the ground" executed by too many critical scholars.
