Space Jam: A New Legacy is definitely a decent family movie. It could have been better, but then again, it wasn't really expected to be an Oscar-worthy movie, and the same goes to Michael Jordan's 'Space Jam'. The plot in the LeBron-led sequel made more sense than its predecessor. It has moral message, something that Jordan's movie didn't had. It had more drama. There was a lot more at stake in A New Legacy compared to the first one. The choice of cast the production surrounded LeBron James with was decent. LeBron James himself was a very good voice actor in the movie, though he needs to put in work on his onscreen acting if he wants to be great. Don Cheadle was the perfect fit for this movie's main antagonist. The Goon Squad were fun to watch, and it was nice that they got the athletes to voice-act their characters. The CGI look for the Looney Tunes was actually nice and fitting in contrast to what most people would say.
As for the downsides of this movie, the father-and-son relationship between LeBron James and his fictional son, Dominic "Dom" James (Cedric Joe) didn't really hit the spot it was supposed to hit. The delivery was bland, and it just dragged the whole message down. The movie could have utilized Bugs Bunny's emotional background of losing the whole Looney Tunes gang and of how he dearly missed and yearned to be with them again as means for a heavier conflict which would have made his sacrifice play towards the end of the movie a lot more emotional and made it a fitting course of action. They also could had Bugs and LeBron clash in that halftime scene which would have been a better way to bring LeBron towards his moment of realization. Cutting off Pepe Le Pew from the film and Lola Bunny's defeminization was totally unnecessary. There wasn't a sense being reunited from the Tunes when they were all back together. There was no spark between Bugs and Lola AT ALL which would piss a lot of fans of the original film. One thing that Michael Jordan's original got right that LeBron's sequel didn't was the NBA connection. They had (aside from Charles Barkley, Muggsy Bogues, Patrick Ewing, Larry Johnson, and Shawn Bradley who were the basis for the Monstars) a handful of NBA players from that time ranging from the likes of Danny Ainge, Vlade Divac, to NBA legend Larry Bird, as well as the entire Phoenix Suns and New York Knicks roster. These NBA players and personalities had considerable screen time, whereas LeBron's sequel only featured NBA superstars Anthony Davis, Damian Lillard, and Klay Thompson along with WNBA's Diana Taurasi and Nneka Ogwumike who only saw the light onscreen as themselves for a couple of seconds. Having Ernie Johnson as the game's commentator was awesome, but that's pretty much about it for the NBA connection.
Overall, 'Space Jam: A New Legacy' is a fun and enjoyable movie, especially for kids. In terms of critical analysis, the movie isn't that bad, but it also isn't that great. I don't recommend this movie for fans of the original 'Space Jam', Jordan fans, and LeBron James haters in general.
