Writer/star Nia Vardalos struggles to repeat the formula of her 2002 breakout hit. This time it’s the elders who have to tie the knot, providing the poorest of plot excuses for a rehash of the original’s crazy family riffs, with added mother/daughter separation anxieties. Cue a Carry On carnival of broad racial tics in which no shoulder is left unshrugged, no hairstyle left unteased, no eyeball unrolled or popular national dish uneaten. I chuckled once, but that lone laugh was sadly neither big nor fat.
