Let's get the bad out of the way first. The narration added to the introduction is completely unnecessary. Like they don't trust the audience to know what is happening. Narrations in and of themselves aren't bad, but this one feels so slapped together... I am quite certain that Jeph Loeb demanded it be put there. And after seeing how "Ultimate Spider-Man" turned out, I'm dreading the fate of this show after episode fourteen of the season airs and Chris Yost and Josh Fine are removed from the project... that was when Jeph Loeb came in, production wise. But, I am confident in the next fourteen episodes, at least. So I'm going to enjoy the ride and hope for the best.
This show does cameos and guest appearances right. We've seen the Fantastic Four cameo before, and heard references to them even before that. Now they make their first full appearances, and the build up helped. The Thing and Human Torch coming to Avengers mansion to play poker is fun, as is the rivalry between the Thing and the Hulk.
But the real meat of the episode is finally seeing Dr. Doom. He was referenced way back in "Breakout Part One" when Iron Man put a stop to A.I.M. trying to sell weapons to Latveria. Now, the good doctor has been on TV many times before. How does this one stack up? Design wise, he is perfect. Writing wise, he is perfect. Voice wise, Lex Lang does a great job... but I think I preferred Simon Templeman from the second season of the 90's Fantastic Four series (and believe me, that is the only thing I would ever prefer from that otherwise horrid show). Doom's use here was pretty simple. He wanted to find out who the Skrulls among the FF and the Avengers were, and he did... well, he found the FF's Skrull. And he put up a pretty badass fight after making it clear to Jan, in no uncertain terms, that her mouthing off at him was pointless. Hank may take Jan home and beat her senseless, but Doom is not that easy. The way the episode ended, I have hopes we'll see him again sooner rather than later.
I am wondering if this show is in the same continuity as Chris Yost's "Fantastic Four: World's Greatest Heroes." The use of Lucia von Bardas in both shows is very similar. In the comics, Lucia von Bardas is a Latverian woman who used to teach at the University of North Carolina in the United States. After Victor von Doom was deposed as the leader of Latveria, the Americans helped von Bardas get elected as that country's prime minister. She then began publicly mending the ties between the two countries. But she started funding supervillains and Nick Fury led a small army of superheroes into Latveria to take her out, and they succeeded. She later returned as a cyborg. In "World's Greatest Heroes" she was re-imagined as an android assistant to Dr. Doom, and is used in the same role here. Now that doesn't necessarily mean both shows are in the same continuity, Yost could be re-using his old idea. But it does make me wonder.
Solid premiere, I look forward to what comes next.
