This obviously goes without saying, "That's My Boy" is horrible.

But a couple reviews say that Milo is surprisingly funny, despite the gross plot twist regarding the character.

“That’s My Boy” is a pretty wretched movie if you want to activate your brain cells, but its busily plotted second half approaches involving. It leads to a big payoff wedding, after all, and it has a large ensemble for support, including Leighton Meester, Will Forte, Vanilla Ice (as himself), a funny James Caan, a cameo by Susan Sarandon and plenty of game-for-the-shame adult players like Peggy Stewart, as a politely naughty grandmother. There’s even one exceptionally good performance, by a committed Milo Ventimiglia as a surprising Marine. - NYTimes

But when Sandler’s willingness to be weird extends about as far as a silly voice, his restraint unintentionally allows someone like Milo Ventimiglia, who plays Todd’s aggressive brother-in-law-to-be, to come in and steal the show. - Collider

It’s not so much the jokes as written but the go-for-broke performances. Vanilla Ice is funny. Milo Ventimiglia, who was not exactly a barrel of laughs in Heroes, is hilarious as Jamie’s super serious soldier brother Chad.

But the truth is, even without pleasant surprises like Vanilla Ice and Ventimiglia, I’m not sure I could ever truly hate a movie that features so much of the adorable Andy Samberg, who acts his little heart out as if this were Shakespeare in the Park. - Time
