Ending is aggressively unsatisfying (SPOILERS IF YA CARE DOC)
As a fan of\nerd for the original Warner Bros cartoons who never thought the original Space Jam was particularly good but still has some nostalgia for it, and who doesn't follow the NBA, I thought this was OK. I feel like it made more of an attempt to play with the Looney Tunes staple as actual characters rather than just merchandising icons, and although some of that is misdirected, I appreciated that.
The final scene was terrible though. If you're going to do a "Bugs makes a noble sacrifice" scene, and that's a big if, you have to come up with a better out than "he's a cartoon character so he can't die", or at least you have to do it with a funnier reveal than they pull off here. It honestly feels like something they changed at the last minute.
