“Defining Moments” (** out of four) was a treacly serio-comedy about the intersection of various lives (Burt Reynolds, Sienna Guillory, and Tammy Blanchard) who realize they are at an important junction of their lives and need to consider settling down, long-term legalities involving their elderly relatives, etc. Earnest and well-intentioned film is also mawkish and has hardly any story to hold it together. Plays more like a t.v. movie than a theatrical release. Film’s only “defining moment” is its Reynolds’ final film but “The Last Movie Star” was a much more fitting movie epitaph for him.
