Will Sloan’s review published on Letterboxd:
Wretched. I wanted to puke hearing Bugs pine for his lost "friends" like Daffy, Elmer, and Yosemite Sam. Those are not his friends. Have the makers of this even seen a Looney Tunes cartoon before? Seeing all these prickly, eccentric characters just grinning stupidly side by side is like seeing loved ones resurrected as zombies.
A movie in the cursed lineage of The Lego Movie and Ready Player One. But while those movies at least paid lip-service to the idea that Intellectual Property is a big toybox for you -- yes, YOU! -- to play in, the thesis of Space Jam: A New Legacy is that what really matters about cultural objects as disparate as The Matrix, Batman, and Casablanca is that they are all brands owned by WarnerMedia. There's a brutally unfunny montage of the Looney Tunes hopping in and out of scenes from various classic Warner-owned movies that feels like an HBO Max sizzle reel. Sad!!!
Minus a thousands points for rendering the Looney Tunes as hideous, uncanny 3D versions of themselves. Also contains some laughable, disingenuous social commentary about surveillance and tech overreach. A five-second shot of the gremlins from Gremlins was presumably included specifically to rub it in Joe Dante's face.
