This collection of the earliest issues of the original Archer & Armstrong is top rate, showing the funny, well-characterized direction that the original Baliant was moving the superhero market toward. The only downside of this first collection is that it doesn't close a (minor) plot thread about a pouch stolen from Aram. If you want that, pick up Archer & Armstrong: The Complete Classic Omnibus instead. 
 First Impressions (0-4). A&A gets off to a rather strange start as their adventures are almost immediately interrupted (in issue #1) by a two-issue trip to Unity. Somehow, it works. Though we scarcely know the characters, they come alive in the Unity comic, as does their strange buddy-ship. 
 In fact, the Unity issues (1-2) are the best of this initial five-issue sequence. Unity is a superb example of how a crossover can be deeply intertwined, but still allow for individual storytelling. We certainly don't get the whole story of Unity here, but the two issues of A&A are a nicely comprehensive whole (and it's overall a great crossover that fortunately was collected in Unity Saga Volume 1, et al). [8/10] 
 Beyond that we get an origin for Archer (0), which has somewhat poor writing but is an interesting story, and a running battle with the Sect (mainly in 3-4). They're revealed as an interesting foe, but the constant fighting gets a bit old, even with the strip's humor [7/10] 
 Trouble in Paradise (5-6). This two-issue story has a remarkably thin premise: Armstrong visits his wife and drags Archer along. Nonetheless, it's an entirely delightful story showing the BW-S A&A at its best. It's hilarious, it shows the great dynamic between the two, and it introduces Armstrong's great wife, Andy [8/10]. 
 These classic issues also have the advantage of beautiful Barry Window-Smith artwork through. 
 Formation of the Sect (2008 Collection). A nice story about the origins of the Sect, but a pretty shallow one [6/10].
