Don MacPherson particularly liked the backup story featuring Amadeus Cho, aka Mastermind Excello. Here’s an excerpt from the review:
Mastermind Excello is a wonderful character. Not only is he defined by his intellect, but he’s a youthful rebel. … [Greg] Pak’s script not only paints him as a genius, but as something of an innocent whose perspective manages to cut through politics and shades of grey. If Marvel doesn’t direct Pak to do more with this wonderful character, and soon, it’s wasting some great potential.
