Wrestle Kingdom 8
Dave Meltzer of the "Wrestling Observer Newsletter" wrote that "by most normal standards, the show was very good", but felt that it did not match the previous year's show, which he called "among the greatest wrestling events of all-time". He praised the final four matches, giving both of the main events four and a quarter stars out of five, while calling the first half "not good" and the tag team match involving the Gracies "kind of an atrocity". In his review of the show, James Caldwell of "Pro Wrestling Torch" wrote that "[t]he big matches delivered, the undercard was hit-or-miss, and the event production was top-notch".
