New Avengers. At times, there's been precious little "new" about the books that carry that title. Ewing's version, starting post-Hickman's Secret Wars, at least had a different concept. Sunspot, through some mechanism I don't know, came into possession of at least part of AIM, which he turned into a radical science international peacekeeping force. Complete with its own island, pocket dimensions to house secondary bases, giant robots, and sleeper agents within SHIELD.
The team is a hodgepodge. Besides Sunspot and the 2 Young Avengers up there, you've got Squirrel Girl, the Power Man Fred van Lente created in the 2000s, a White Tiger, Clint Barton Hawkeye (although this is the era where Marvel was trying really hard via caption boxes to convince us Kate Bishop was cooler than Clint Barton), Songbird and a couple of other characters I think were new, including the daughter of Dr. Yinsen (the guy who saved Stark's life in that cave), herself a genius scientist.
Though the Master (the Reed Richards of the Ultimate Universe, now crazy and evil and somehow spread across the new multiverse) is the overarching bad guy, the team spends as much time dealing with attacks by SHIELD. Once, because Rick Jones exposed one of Maria Hill's stupid plans and Sunspot gave him asylum, and after that, because they acted on U.S. soil, and that was apparently something Sunspot promised not to do.
The book manages 5 different pencilers in 18 issues. Gerardo Sandoval draws the first arc, involving Hulking learning he's some pre-destined child meant to unite the Kree and Skrulls. Sandoval's stuff is sharp and angular as always, but the heavy blacks he favors work well once Wiccan starts showing outward signs of being possessed.
Marcus To draws the 3 issues tying in to Avengers: Standoff (the story where it turns out Maria Hill was sending super-villains to some fake community and messing with their heads so they thought they were just regular people), except this books' issue involve a patriotic kaiju and Songbird turning on Hawkeye when he tries to defend Rick Jones from SHIELD agents. To's work is solid superhero stuff. He draws a decent giant robot/giant lizard fight.
Paco Medina handles the final arc, when the Master unleashes his group of weirdos (set up as sort of a twisted reflection of Sunspot's bunch) at the same time SHIELD attacks again. Medina's art is, also, pretty standard superhero-style art. Faces are rounded and softer than in To's work, physiques a bit more exaggerated. But, in general, all the artists do a solid job conveying emotion and action as needed.
Ewing comes up with a lot of neat ideas - threats from an earlier cosmos, a U.S. project to turn a hyper-patriotic soldier into a Godzilla - but I stumble at his portrayal of Sunspot as this brilliant mastermind, always 10 steps ahead of everybody. SHIELD asks Sunspot to let Hawkeye be on the team, acknowledging he's there to leak info to SHIELD. Hawkeye sells it by introducing himself as being there to spy on them.
In reality, Songbird's the real double-agent, except Da Costa anticipated that, so she's actually working for him by pretending to work for SHIELD. He fakes his death to draw out the heads of rival AIM factions, who he's certain will use a device to freeze time during his funeral to confirm his death, and lining the coffin with secondary adamantium will block the device they'll definitely use, so he's totally prepared.
Now, this is mostly an issue with me. I don't buy "I perfectly anticipated your every move," in stories. Not in movies where regular human serial killers stalk other regular people, and certainly not in a world with as much weird shit as the Marvel Universe. Not when Tony Stark says he's a futurist and so the heroes need to embrace fascism, with him as Chief Muck-a-Muck. Not when Reed Richards says he made psychohistory a reality, and MATH told him Negative Zone prisons were the best way to go. Hell, the Mad Thinker's whole shtick was thinking he'd perfectly mapped out all the variables, then getting tripped up by something he couldn't measure or account for.
If I can't buy it with them, I certainly can't buy it with Sunspot. Might as well tell me Speedball or Molly Hayes are masters of intrigue and counter-espionage. Especially when Ewing keeps going to the well of "things look bad, but actually is going perfectly according to Sunspot's plan." The first arc is probably the best precisely because Ewing doesn't try that. The team thinks they've dealt with the problem of a powerful sorcerer from a previous iteration of the multiverse, but he's actually hidden away inside Wiccan, who has to pull out victory at the last second on his own.
