There's a lot of innovative material in this volume, stuff that is foundational for the modern X-comics. The writing's not always the best, and the '90s artwork is an acquired taste, but it still is an interesting read.
The End of the Beginning (NM #98-100). Back in the day, I wasn't fond of this arc because it totally deconstructs what was left of the classic New Mutants team. Reading it again, I can better appreciate it as the start of something new (though it still has scripting issues). But, there's lots of nice setup for all these new characters, highlighting potential character arcs for them. I can even appreciate the dynamism of Liefeld’s art over the standards for the time [4/5].
Kings of Pain (Annuals). This is an intriguingly timed annual crossover, set just before the start of X-Force, in the middle of the X-Men's Muir Island Saga, and near the end of the original X-Force run. It also makes good use of continuity, reusing X-Force's Alliance of Evil and offering what was then the first big return of Proteus. With that said, it's a kind of "meh" story. The majority of it is a long MacGuffin hunt, as an entirely flat and dull character called Harness uses another called piecemeal to reconstitute Proteus, followed by a dull fight with Proteus. The reality-warping of Proteus as he creates a mathematical dimension was probably interesting at the time, but now has been seen in every Proteus resurrection, most recently the newest Astonishing X-Men [2+/5].
The Killing Stroke (Annuals). Freedom Force was a fun conceit for the X-comics in the late '80s. This is a good last stand for them [3/5].
Shorts (Annuals). The shorts in the annuals are generally good, because they touch upon peoples who weren't getting enough attention in the main comics. It's thus great to see a final few appearances of the "X-Terminators", even if the stories are shallow. However, it's Mystique's story of laying Destiny to rest that really knocks it out of the park [3+/5].
(And despite their general mediocrity, it's great to finally have these "Kings of Pain" annuals in a collection.)
The Beginning (XF #1-2). The first couple of issues of X-Force are strong character pieces that also remind us of the core fight between X-Force and the MLF [4/5].
Spider-Man (XF #3-4). Unfortunately, X-Force's second (short) arc brings everything to a screaming halt. The dust-up with the Juggernaut is dull and overly long. Worse, two of the three issues are printed sideways instead of up and down. They're sufficiently annoying to read that I usually skim them when I get to these issues [2/5].
The Brotherhood (XF #5-7, 9-10). This new Brotherhood story is surprisingly strong. That's in part thanks to the return of old villains, as we got a mash-up of the Brotherhood, the Morlocks, and Sauron. It's in part due to the surprise of Cannonball's death and rebirth (and the fact that it's part of a larger plan). But it's also that we get X-Force's brutality on full display, as both Sauron and Masque are killed, marking a real change from classic X-comics. Of course, both those deaths have been reversed, severally undercutting this comic; the Masque resurrection is the more annoying of the two, as Chris Claremont just decided he wanted his character back and didn't even try to explain it. Still, back in the day, this was pretty bad-ass [4/5].
Flashed Before My Eyes (#8). The Cable backstory dropped into the middle of the Brotherhood story is a kind of dull heist plot, but it does have several interesting elements: it shows the Wild Pack back in the day; it reveals Cable's mercenary tendencies; it shows him as a a time traveller come back for Cannonball; and it has great Mike Mignola art [3+/5].
X-Tenuating Circumstances (#7, 9-10). This Weapon X story has no depth, just a bunch of fighting. It also doesn't go much of anywhere, other than Kane (whoever that is) learning who Stryfe is: and back in these early days of X-Force it seems like Liefeld was suggesting that Stryfe was a future Cable [2/5].
Know Your Enemy (Annual). This Dan Slott short from the first X-Force annual is a dull listing of possible enemies that doesn't really deserve to be called a story [1/5].
Everything Hits The Fan (#11-15). This story, which marks the bridge between Liefeld and Nicieza's plots is interesting because it's so multi-faceted. We get a new "Weapon Prime" stalking X-Force and a climatic battle with Tolliver and some interactions with the Externals. There's a lot of good foundational stuff here, even if the scripts sometimes suffer. With that said, I find the Tolliver stuff generally weak. He's got a dumb name and he's a villain's whose renowned mainly for the fact that he wears a big hat. Compare this to the introduction of background villains like Sinister in this era and you see what Liefeld was trying to do and falling far short of. Also, the fact that the Domino introduced in the waning days of New Mutants was an imposter is ... entirely bizarre. Clearly, this is something that came out of left field, not out of careful plotting. [4/5]
Cable: Blood & Metal. Cable's initial mini-series is one-part flashback to the Wild Pack (now the Six-Pack due to trademark concerns) and one part modern hunt after Stryfe. And none of it's particularly interesting. The big confrontation between Cable and Stryfe should have been fundamental, but it turns out to just be minor setup for the X-Cutioner's Song a month or two later, which addressed the question of who these characters are at a much deeper level. Still, there's some nice development for Kane [2+/5].
