There will be some Mr. Gumbys who kneejerk and say "durr it am Groundhog Day ripoff durr." Well, Groundhog Day was a "ripoff" of the story/short film 12:01pm, and cries of "ripoff" are typical really of 12 year old boys who are just starting to see the patterns of life, are angry due to their biological changes, and who don't yet know that life does indeed have precedents. Moreover, the film namechecks GD in addition to Edge of Tomorrow (which itself was an adaptation of All You Need is Kill). What we are seeing here is a different take on the emerging time-loop narrative. The concern then is what you do with it. GD and EoT are classics, and I understand that Palm Springs is great as well. Happy Death Day was fun, the sequel less so (likewise the 12:01 feature length TV movie). This new movie here is closer to EoT in quality.
All of the performances are very strong and naturalistic. The visual quality also goes for a wide and naturalistic color palette, sometimes with soft lighting, sometimes with harder lighting. The DP also changes things up with only occasional handheld to go with tracking shots and stationary bits. It's paced in a breezy way, which works well with the summertime frame: they may be stuck in a mundane day, but there is a casual joy to the little bits that they find, reflected in the pacing. As to the script, it is not one the level of deepness that GD has, but it strives for something different structurally in the final act (and I do wish they had done a little more with Margaret at that point). There are funny moments, cute moments, and some sad moments.
Ultimately, it is worth your time.
I must criticize the one star and two star reviews that exist so far. The one star review came from some Mr. Gumby-type complaining about "woke pandering". Uh, no, Dunce-inane, that wasn't "woke pandering." The fact that you thought so, and felt the need to post a negative review, proves that the people who hate "woke" have no idea what it means, in addition to being simultaneously insensitive and snowflakes. Grow up and spend some time at the library. As to the two star review . . . seriously, you're going to trash the movie because it dares to be a metaphorical take on grief? You, also, should spend some time at the library.
