6: Vs Kurt Angle, 2003
Brock Lesnar's match with Kurt Angle at SummerSlam 2003 is not exactly what you would call bad, largely because these two men are incapable of delivering such a match when they are in the ring together, but it fails in comparison to their earlier encounter at WrestleMania 19.
The two men suffered as a result of some questionable booking at SummerSlam 2003 and the match was largely forgettable because of it. The match featured Vince McMahon coming down to the ring and hitting Angle with a chair, and several poor refereeing decisions.

The ending is notable for featuring the unusual sight of Lesnar tapping out, but this is one of the weaker matches in the two's collection together.
