I saw this a few weeks ago and am still "processing" it, which I think is a good sign as there are some images and tonal aspects of the film that linger longer than its time on screen. That said, my initial reaction was a bit mixed. I hadn't seen any of Argento films after 'Two Evil Eyes' in 1990 and the overall look and loss of artistry was a bit jarring. It has a "made-for-TV" feel throughout and some rough CGI that really drags it down. The stylised "otherworldliness" of Suspiria, Inferno and many other Argentos (including some of the earlier giallos) is sorely lacking, with some quite everyday locations and characters (some of the witchy characters are basically goth teenagers that hang out at the shopping centre). Mother Lachrymarum herself also lacks serious gravitas: yes, she's be touted as the youngest and most beautiful of the three mothers, but her overall look and presentation seems more appropriate to soft porn. This, along with some very vicious violence that lacks the stylised aesthetic of his older work, contributes to an overriding tackiness in the film. Whilst some of Argento's 80s films may have sometimes seemed lurid, they were never tacky.
And yet, the extremity of the violence is what in some ways lets you know that this is an Argento, and it turns out to be one of the most hectic and crazed films I've seen of his. What it lacks in charm it makes up for in feverish brutality. You may call it undisciplined, but the accumulation of outlandishness in this film starts to have an effect and as it becomes more and more madcap, it also becomes more entertaining. The culmination is one of the most OTT and blood-soaked (until Luca Guadagnino's Suspiria came along, which possibly takes some inspiration from Mother of Tears). Along the way a fairly compelling mystery is spun with some cardboard characters, but the ending delivers a pretty satisfying pay-off. I'm glad Argento concluded the Three Mothers trilogy; whilst it might not have been the film we expected - or wanted - it still delivers, and rounds out the mythology without sullying the legacy of Suspiria and Inferno.
