Actually, Cornette is the one responsible for the fifth star. The star rating system as originally constituted maxed out at four stars, but Cornette and the friend who came up with the system agreed that the Lawler/Funk no-DQ match broke the scale and deserved an extra star.
Also, Hogan’s star was on the wane as his 10 year old character had grown stale and passé especially in the South, which expected a higher level of wrestling than the cartoon stuff that Hogan liked to shovel.
Baltimore is not in the South.
I like this match a lot. For me, it's a tossup between this and the Desert Storm Match as Hogan's best. And I think Vader kicking out of the legdrop at one and getting a visual pinfall off the powerbomb did a good job in repairing the damage done by Hogan popping up at the Clash. That pre-match promo, on the other hand...oh boy. He said "brother" no less than 23 times (well, "brother" 22 times and "brothers" once) in the span of three minutes. I don't even think Shawn Michaels said "brother" that many times in his Hogan on Larry King parody.
