If written well, there is a lot of potential for the plot to develop into something really good. However, similar to the live-action Iron Man and 2, it appears to center on the idea that individuals are constantly attempting to steal Tony Stark's technologies. Although I suppose there will always be those who desire that kind of technology, something alternative would have been preferable. Thankfully, the creators made an effort to bring the anime as near to the film as possible, since episode 2 of the anime depicts Tony's chest as having the light of the core.
It seemed respectable to me, and the character and outfit designs were really well done.
Unlike other anime openers with lyrics, this one has only music for its opening and closing themes. This was a rather welcome shift, and I thought the opening and closing pieces were great because they occasionally added a sense of urgency and various tempos. The sound effects were great, but once more, ardent Iron Man fans won't hear the remixed sound effect of the repulsor rays, which is far more spectacular in the live-action film.
For me, this was the more disappointing aspect. The way in which characters were introduced fell short of my expectations, and the arrival of one particular female protagonist was a bit too sudden. (I'm confident that you can all figure it out on your own!)
My heart raced throughout the first episode, but I was thoroughly captivated the entire time. The action scenes were well-executed, and the small cliffhanger at the conclusion of the show whetted my appetite for more. But as episode 2 requires Tony to battle a fresh sign of the zodiac, it's reasonable to assume he has ten more signs to overcome. This lessened the suspense the anime could have offered its audience, which in turn diminished my enjoyment of it as a whole.
It does appear promising, as I have said. I sincerely hope that the upcoming episodes will contribute to this anime becoming one of the more popular ones this season!
