Angst? What Angst?: Subverted with Lian Harper. She's understandably freaked out when Dreamslayer summons her in Convergence: Titans but she manages to roll with everything that happens after Arsenal saves her. She doesn't even seem fazed by the fact that, since the last time she saw her father (which to her had just been earlier in her day), he now has a prosthetic arm.
Author's Saving Throw: The event seems like this trope personified, to the extent that some have called it "A love letter to the fans."
The event is a series of stories revolving around various past versions of DC's characters, who have been plucked from the timestream by Brainiac. The general sense seems to be that DC wanted to go back and give a satisfactory send-off to the Pre-New 52 timeline, as well as answer some complaints (with the writer of the Titans tie-in explicitly saying he wanted to reverse the horrible things that had been done to Arsenal and Lian during and after Cry For Justice). Plot points include:
The beloved Wolfman/Perez-era Teen Titans being featured (rather than one of the more recent, controversial incarnations) with the creators promising to follow up on a storyline between Kole and Jericho that originally went nowhere.
Ultimately, the biggest Throw was made at the very end; Crisis on Infinite Earths is undone, allowing all universes to exist once more. All of our favorite characters, even if some of them are changed, are now free to have stories told of them.
Bizarro Episode: Both issues of the Supergirl Matrix tie-in, which are written by Keith Giffen, notorious for writing satirical stories about the DC Comics staff, current status quo, and characters.
Broken Base: The ending of Convergence #8 has sparked a lot of debate among fans. Some say that the original multiverse is back and infinite now, while others see the art as depicting the New 52 multiverse as an evolved version of the old one. DC has not been clear in this regard, with author Jeff King stating that everything ever published is now in continuity and out there somewhere, while Dan DiDio seems to view the ending differently than King, but won't be too precise, preferring to let fans debate. At this point, it's going to take further published stories to clarify the situation.
Idiot Plot: Convergence: Superboy #1 & #2 work on this principle. Superboy is set against the Kingdom Come Superman, Flash and Red Robin. The latter three attack Superboy without saying a word edgewise and then suddenly say they come in peace. Naturally, Superboy doesn't buy it. The book then goes into detail about how Superboy is in the wrong because he refuses to give up or surrender to the KC heroes. Except... he has a point. All Superboy knows is that whoever took their cities hostage has stated that anyone who loses their fight will see their city destroyed, so he's fighting just as much from anger as fear. He also has no reason to believe anything Superman tells him, because for all he knows, this is an evil counterpart or something. When Superboy flat out states all of this, the characters still treat his misgivings as selfish and wrong because the three older KC heroes supposedly have a better chance at saving everyone. But, yet again, he has no reason to trust them.
Just Here for Godzilla: Many readers are happy to see their favorite characters again in their pre-Flashpoint versions, if only to see them get a proper closure to their stories.
In Convergence: Batgirl, Stephanie Brown and Cassandra Cain are shown to be living together. Stephanie also refers to Cassandra as "honey", paying a little fanservice to the popular ship.
In Convergence: The Question, there's a rather similar situation between Renee Montoya and Helena Bertinelli, who are also living together, and talk to one another like a married couple. It's likely a Mythology Gag to the Justice League Unlimited cartoon, in which Helena and Vic Sage, who's Renee male predecessor in The Question mantle, were a couple.
Like You Would Really Do It: Many fans find it hard to believe that this is the actual last time DC will do anything with these versions of the characters, considering how the company has become prone to the Cosmic Retcon trope, and considering that they had attempted something similar with their DC Retroactive mini-event back in 2011. Turns out to be correct, when this event in fact goes the complete opposite extreme and makes every story, everywhere, canon.
The main Convergence book is starting to get this reception mostly due to the first two issues (#0 and #1) only repeating the main premise of the book and focusing more on the Earth-2 characters than anything else. Things may be starting to improve as issue 2 has been noted as having some strong moments: the Earth-2 characters having a focused plan, E-2 Thomas Wayne meeting Pre-Flashpoint Bruce Wayne and having a bittersweet quiet moment alone while E-2 Dick Grayson sees a version of his wife still alive while he has tea with Pre-Flashpoint Alfred.
The event overall has garnered this reaction. Many fans were happy at seeing past versions of their favorite characters as well as the attempts to resolve some unresolved arcs, especially fans of the Titans, Oracle, and the Superman/Lois Lane marriage. However, many felt the books lost some impact due to continuity and editing errors, which were especially prominent in the main title.
Strawman Has a Point: In Convergence: Superboy #2, after the Kingdom Come heroes face Superboy, he becomes angry and determined to fight them despite their pleas to work together. Everyone (even Dubbilex, who narrates the book) states how irrationally and angrily Superboy is behaving... except Superboy is right for several reasons. First of all, they attacked first, so their pleas for peace seem hypocritical and petty after they were the ones who attacked him with Kryptonite gas. Second, Superboy has no idea if these guys are Evil Counterparts to the heroes he's familiar with. Third, the only thing Superboy knows is that anyone who loses their fight will see their city destroyed. When he asks why the KC heroes (if they're so noble) didn't surrender right away, they say because they have a better chance of figuring things out. Except, there was no way they could have known anything about Superboy or his world to make that judgment. Dubbilex does eventually point out that Superboy has a point, and then communicates with him telepathically to let him know that the version of Superman he's facing is indeed a hero.
Both Harpers in Convergence: Titans #1. After all the crap Roy did and went through, after finding at least some semblance of peace, Lian gets resurrected and Roy is told if he ever wants her back for good he has to fight Troia and Starfire. And Lian, in her very first appearance after she was brutally killed off in Cry For Justice and used as a justification for Roy's FaceHeel Turn, is now at the mercy of a demonic being who quite literally has her life in his hands. She's terrified and begging her dad for help, but at the same time she's also forced to watch as her father fights Donna and Kory, her surrogate aunts, and he's doing it for her. Donna is even the closest thing to an actual mother Lian's ever known so she's watching her family tear itself apart over her. God damn somebody give these two a hug, or better yet, just let them hug each other. They get their hug.
