Six theme answers today, plus a revealer! Home-body, home guard (?), home game, homeboy, home computer, home port... you get the picture. Some are definitely better than others, but with so much theme material, I suppose that's only natural. My mistake came when I guessed that the smallest NATO member might be Ireland (it's ICELAND), so I ended up with some "home ire." Heh.
Some of the fill, too, was better than other. Take MENT (14A: Suffix with refresh or replace), or HELOT (16A: Spartan serf), for example. That first is pretty weak, and the second is some deep Greek! And for what? MENT crosses REORG and ANDIE, which both cross EGESTS, and while I applaud the courage to reference "Dawson's Creek," I think that all that just to get "homebody" and "home guard" (whatever that is) might not be worth it.
I liked NUZZLES (26D: Shows some affection), but that crosses SEZ, ZZZ, and LII. And elsewhere we find ONER (47A: Long, single take, in filmmaking)? COS (60A: Stock listings: Abbr.). IMAGO (53D: Insect stage)? and ZIA (41D: 1980s Pakistani president)? Sheesh! I usually don't like to be overly negative about a puzzle, but that's a lot of ... let's say, unusual entries.
1A: Country invaded in 2003 (IRAQ) - C+, elevated slightly because it uses the word "invaded," which paints us as the aggressor nation that we often are.
Favorite: PRIORY (29D: Religious abode). Good word.
Least: PAH (65D: Part of a tuba's sound). Oom.
I found this one rough. I've heard that some find this kind of theme to be pretty much played out, so I guess the thinking is that if you have a ton of theme, that will make it more worthwhile. I'm not sure that works out in the end.
