Critics

 * Jesse Schedeen of IGN - (This) episode made an already crowded cast of guest stars even more crowded. And because of that, it felt as though Penny's family drew the short straw in terms of screen time...Having three sets of relatives visiting at the same time is a little much to handle in one 22-minute episode...The family drama was generally entertaining despite the limited space afforded most characters...Eventually the wedding itself rolled around. The result was pretty textbook sitcom wedding fare...But in the end, it was Sheldon who stole the show (as he so often does). Leonard and Penny's vows were sweet and all, but it was Sheldon's rare admission of love that really delivered the feels. He so rarely admits his love for Leonard that those moments where he does become all the more memorable.
