It was bad enough in 616 verse he shagged Henry Hellrung because Henry looked like him (long story), so it's wack that he does it here! But at least with Henry, there was some heft in the relationship - Hellrung was the person that became his AA sponsor.

Whereas in The Ultimateverse, I honestly don't know what Stark's fiancée bought to the table.

If you can, read the novelisations of the comics. For one, the books are longer, and more in depth. Also, it seems the writers like Tony.

The first graphic novel is a bit sluggish, because they are just establishing the characters, then they take off with a bang.

The Avengers cartoon is quite good, and actually dovetails into the comic quite nicely.
