Milo Paulus’s review published on Letterboxd:
Yes, I went to see this in the theater. Yes, it was in the middle of the day. Yes, I paid money to see this. Yes, I was alone, and yes, I am not proud of my actions. After being utterly baffled by the fact that this ten-year-late sequel got decent reviews, I decided to check it out. My eyes hurt from watching this. Not really for the reason you might expect, but because I was rolling my eyes so frequently and ferociously. This nauseating soap-opera is two hours of plotless nonsense with awfully written and performed musical interludes with a 30 year apart parallel timeline solely because Meryl has such a disdain for the original film and most likely didn't want to come back, but they still decided to fully advertise as if she's got a decent role—spoiler alert, she has one scene . . . and you have to wait a long, long while to see it.
I fortunately don't remember anything from the first one, so I can't really compare the two, but I am sure this one is even worse. Here We Go Again indeed; not much has changed. The plot is still contrived, cliched and silly. The entire things is still a ridiculous fantasy. Everything still feels like a glitzy, glib, over-produced extravaganza. ABBA's fantastic songs are still butchered and shoe-horned in. And Pierce Brosnan still sings, dances and acts like hell. The original was the highest grossing film in British cinema history at the time, and this has now become the highest grossing opening box-office weekend for Streep, Seyfried and Cher. Fuck me. Just an overall insult to the musical genre.
