The first 3 episodes of iron heart are actually incredible.
First of all the review bombing coming from racists, sexists, and general haters who hate diversity of all kinds will never give you the full scope of what kind of show this is. If you're reading I encourage you to actually watch the show rather than letting haters dictate how you should feel.
As for the show itself it's does an incredible job at continuing where we left off in Riri's story and gives us a more in-depth look into what drives her character what obstacles stand in her way.
When it comes to her place in the iron man legacy she's made it abundantly clear that she respects Tony's mind and accomplishments and wants to complete his dream of putting armor around the world but struggles to do so because of her lack of resources.
These first 3 episodes really gets you invested in her abilities as an engineer and definitely makes me eager to see what's next.
