I am not an experienced reviewer, nor do I claim to be; however, I thought it would be fun to write a review of the movie of my own, to throw my own opinion into the ring.
The LEGO NINJAGO Movie definitely stands out from the rest of Warner Bros.' LEGO-verse films. As it is the first time that one of LEGO's own IPs are being adapted to the silver screen, it has big shoes to fill, in order to see whether or not more LEGO-unique IPs could be made into successful movies. It's unfortunate, then, that it is a downgrade compared to the previous films.
Firstly, I enjoyed the main story of the flick. While I do have to agree that certain elements of it are retreads of the relationships found in The LEGO Movie and The LEGO Bat-Man Movie, as well as the fact that it's the third theatrical LEGO film to include daddy issues, I still enjoyed it regardless, and thankfully, the story makes up the bulk of the film. Dave Franco's Lloyd and Justin Theroux's Garmadon play off each other really well, and you really get a sense of progression with the relationship throughout the film. That being said, the ending is quite rushed, and doesn't resolve the relationship naturally in my opinion.
The film is, of course, gorgeous. The LEGO films have always had quite a bit of polish put into both their architecture and landscape as well as details real to life (scratches, discoloration, and fingerprints), and this film is no different. It has, however, a much more organic landscape compared to the previous two, and it really does look both real and beautiful. I don't think anyone can deny the fact that, visually, The LEGO NINJAGO Movie is an amazing looking film.
Musically, however, it doesn't quite live up to what the visuals present. There isn't really a memorable score to speak of, which is unfortunate, as I would have personally found an East-Asian inspired soundtrack to have been interesting and unique. Instead, you get a lot of pop-rock and pop tunes, which, while bad, aren't exactly stand-out among the crowd of family films. However, this is a minor complaint. And no, Tailor Swift's "Bad Blood" isn't in it.
I think one of the biggest problems of the film is it's quality of jokes. None of the jokes really land, unfortunately, and some of the jokes in the trailers are actually made worse in the film. For example, in the first trailer, there were 3 stand-out jokes: "garmadon, Garmadon, GARMADON!", "Luh-Loyd," and the bride leaving the groom behind. What makes "garmadon, Garmadon, GARMADON!" funny is that each time Garmadon's name is said, the voices get higher in pitch. However, in the film, you have the lowest pitched of the "Garmadon's" repeated, Garmadon yelling "What's my name?" between each time his name is said, and loud music playing over all of that, ruining the joke. Additionally, the bride and groom joke is cut entirely, leaving only "Luh-loyd" intact; however, by this point, you've heard the joke so many times that it's humorous value has been lost.
Another major problem is how far the other characters are pushed into the background. The character dynamic between Lloyd and Garmadon is great, yes, but that doesn't change the fact that the other ninja don't get nearly enough on screen to really know them or care about them. Fred Armisen's Cole, who many fans would have hoped the film expanded upon, only has 2-3 lines throughout the whole film. You are supposed to infer that Kumail Nanjiani's Jay has a crush on Abbi Jacobson's Nya with only one line. It is never explained nor even really brought up why Zack Woods' Zane is a robot. Yes, I know you can look up the lore to find those answers; however, this film is, in fact, a reboot, and as such, should explain such things in order for not only Ninjago fans but regular audience members to make sense of it.
Personally, I would give the film a 7 or 7.5 out of 10. I don't think the film is as bad as many critics are making it out to be (it is by no means a 48%, as it says on Rotten Tomatoes as of writing this review), but at the same time, the film does have some noticeable problems, especially when compared to be LEGO films before.
