Ryan Reynolds sure is a cutie — when he works with material that plays up his goofball, wholesome charm. But there’s not much of that in Definitely, Maybe. As the about-to-be-divorced dad of an adorable moppet (Breslin), Reynolds’ Everyman-ness inches too far toward bland. Still, Maybe is several cuts above your average rom-com, thanks to Weisz, Elizabeth Banks, and (especially) Isla Fisher, who play his vibrant, fully drawn past loves. EXTRAS Deleted scenes, two making-of docs, and a lively commentary in which Reynolds sings Fisher’s praises, saying she has the ”mouth of a sailor.” B+
