In short, is this a masterpiece? No. Is it groundbreaking? No. But what it is, is entertaining and fun. As some critics have pointed out, it feels very 90's. Which I believe works.
It has a great cast, cool yet admittedly wack concept, fun set pieces and a nice soundtrack. However, what is of course the best part of the film and it's main selling point: killer aliens and Chris Pratt. The aliens have a nice design, and are perfect for the summer blockbuster style.
Pratt is excellent and continues prove to be an actor who feels like he's in the wrong era, the perfect 80's and 90's leading man.
The story isn't all that deep or thorough, and the characters could use work. But Pratt delivers and the cast is still fun.
Perhaps one or two too many jokes, and again the writing is far from great, but the film does acknowledge what it is whilst still providing some emotional stakes.
J. K. Simmons is also excellent as always.
All in all, a decent and fun alien/monster adventure film. I feel it could've bettered from a non-PG-13 rating.
Biggest issue was the overuse of CGI. But sadly that's the ways movies seem to go these days.
That said, with all the garbage Hollywood releases, and with all the comic book and franchise films, and of course you award winners, it is nice to have a film that doesn't necessarily feel those categories. In short, a fun film. Shame it released on streaming, would've been better in the cinema.
Don't buy into the overly positive or aggressively negative reviews. This film ain't that bad or that amazing (objectively) but is exactly what you want from a sci-fi summer blockbuster.
As always decide for yourself, but if you're reading this and need some swaying: I recommend The Tomorrow War. 7.5/10.
