2008’s Mamma Mia! was somewhat defiant in its shrugging off of the demands of self-serious audiences, presenting an escape from the evils of mundanity, logic, and pretension. It wasn’t something to wrap your head around, for in its haphazard lunacy it delivered tenfold precisely the ecstasy that its audience requested. Now ten years later, such escapism isn’t a mere trifle but a necessary antidote to ensure our sanity and survival. Mamma Mia! Here We Go Again, its slightly more sedated sequel, is like a soda administered during a diabetic collapse.
