'' criticized the relationship between characters Leonard and Penny, writing that they "certainly don't have some passionate, Ross and Rachel-style 'will they / won't they' romance, with fans dying to see them together. Even now they're married, it's a weirdly anti-climactic payoff - and it doesn't quite feel right that they're together." Ashley Bissette Sumerel of TV Fanatic wrote that "For a rather serious season premiere, "The Matrimonial Momentum" is still a lot of fun".
