Yes, Yes, a thousand times yes...... FF #38 is my favorite FF issue of all time and I have been following the FF for 55 years! Not only that, but Medusa's capture of the Invisible Girl in this issue is my single favorite page in all of the FF history! It was Medusa who really should be credited with the FF's first defeat, as it was her capture of Susan Storm that made it all possible!
While we are at it, the Frightful Four have become a laughing stock in recent years. Medusa should have stayed with the evil FF, as they had their most success when Medusa was a member of the team! All Stan needed to do was to give her some psychic power, to go along with her deadly hair, so she could negate the advantage of Sue's force field.
