Iron Man has yet to enter a particularly good era.
I was really looking forward to the titular War of the Supervillains, but it turned out to be a milquetoast affair with barely any villains, and its milquetoast motivations were clearly up for revision with every new issue. Whether Mike Friedrich had a plan for the Black Lama (ugh)'s machinations that got scuppered mid-voyage, or he was making it up as he went along, the final product is not a cohesive or enjoyable story.
Tony Stark's personal life ambles along similarly, with characters introduced without purpose, forgotten about for several issues at a time, checked in on with pointless "Meanwhile..." cutaways that go nowhere, etc. Pepper and Happy remain the most interesting and well-developed members of the supporting cast, as befits the longest-serving veterans in that role, but for whatever reason the narrative wants to keep sidelining them; maybe there was an editorial disfavor with their status as a married couple (too grown-up for comics?) or the fact that they know Iron Man's secret identity and are okay with it (too much nuance?), but sadly these are the two elements that make them most interesting to me. There's a lot of pathos in knowing that their lives will always be in a bit of an uproar if they stick by Tony, yet they choose to do so out of undeniable loyalty and friendship. Sadly the writers keep finding reasons to obviate that loyalty.
Firebrand continues to intrigue me as a rival for Tony. There's something very appealing and ripe for storytelling about our hero, who serves as an icon of American industrialism and all the baggage that comes with it, going up against an antagonist who represents distinctly left-wing values and causes. There are hints of sympathy and empathy from Tony's perspective towards Firebrand's, such that the writers clearly intend for readers to share those sentiments, but they're all too often eclipsed by Firebrand's thin characterization, over-the-top pronouncements, and overall unpleasant demeanor. And then when he gets drawn into the bizarre and fantastical climax to the War of the Supervillains, it all becomes rather pointless. A villain with a lot of squandered potential; I'm no expert in the Iron Man timeline, but I don't feel like he does much between this point and a minor revival in the Heroes Return era of the 90s, so I'm not getting my hopes up that some writer figures out how to use him well in the near-term.
Elsewhere we get the requisite Freak multi-parter, Jack Frost's very welcome transformation into Blizzard, and the return of the Controller in an interesting story where he's shown to be in a sort of codependent homophilic relationship with an unhoused man named Scrounger, which remains underdeveloped. (Spoiler, but how does scrawny Scrounger whisk Controller's inoperative exoskeleton bod away from the scene of his last battle with IM without anyone noticing?) Sunfire appears in his capacity of "not a bad guy but grating and set against our hero because reasons," and while the story comes around on him eventually, his "hotheaded nationalistic Japanese man" schtick is getting less and less supportable as we go along.
