I usually am not the biggest fan of the early era of comics but I found the Fantastic Four comics included in this collection to be quite amusing, I would rate all of the comics included in this retro first half at around 3 stars. It was interesting to see Agatha's origins.
The second half I really enjoyed, as it is actually just the full run of Midnight Suns, a comic which I was intending to read anyway. This arc features more characters who I enjoy quite a bit (namely Magik and Nico Minoru) and the setting of Strange Academy. I thought some characters were a little stagnant (Nico is worried about making do without the Staff of One, Wolverine hates magic) but overall liked the art and storyline a lot, I would probably rate this arc 4-4.5 stars on its own.
I'm knocking my ranking of this TP as a whole down to 3 stars though as I do not love it as a collection meant to explain Agatha, particularly as a marketing tie-in to the show Agatha All Along. I understand the need for brevity - an omnibus of all of her appearances would be a much different undertaking than this project - but especially considering her current role in the MCU, it was bizarre to me to touch so little on her relationship with The Scarlet Witch. I would have preferred at the very least a written summary and names/numbers of the other issues she appears in between those comics included in this book (like how is done in the X-23 omnibus).
Overall enjoyable, definitely made me interested to watch Agatha All Along and play Marvel's Midnight Suns, so at the very least Marvel did succeed with their marketing ploy, even though I think it easily could have been improved.
