I had heard so much bad press about this one that I didn't have high hopes. In addition, my store got a damaged copy of NA #50, so I ended up getting it for free (there is a fold on one corner of the book). Due to those factors, I didn't think was so bad. There is some dialogue lifted straight out of Dark Avengers #1, but I've come to expect that in the Bendis verse. One neat detail pops up again when Ares lingers for a moment after Norman Osborn decides to leave the New Avengers to the Hood's gang, implying that maybe our God of War has some second thoughts about his allegiance? I'm not sure. The New Avengers' takes on the Dark Avengers kind of made me laugh, since the internet fanboys have been saying the New Avengers are fakes for years, so now the shoe is on the other foot Wolverine, Echo, and Spidey! :) I thought the splash pages by various artists were nice, and the best was of course Steve McNiven's Spidey page. Bendis really made it work too, with Spidey wondering why he chose this incarnation of the Avengers to join, pretty funny stuff. The book closes with Clint Barton going on the news to call out the Dark Avengers and Osborn. I like how quickly we're getting to this confrontational point, but how the heck will the Dark Avengers remain a working concept for a comic if they face off against the New Avengers anytime soon. And now that the NA know about the DA, I can't imagine they can stall the fight too long.
One other note, in typical Bendis fashion, the Hood's army of goons actually beat the Avengers and force them to retreat, continiuing the awesome New Avenger track record. BTW, I'm not giving the NA any credit for Secret Invasion either, since Thor and Osborn were more responsible than anyone else for ending it.
Billy Tan's photocopied panels were pretty blatant, I'm surprised a professional can do that and still get work.
