I've read the manga twice so I'd say I'm a big fan, though I never bothered to watch the anime, on a whim I watched this with some of my friends because why not and honestly this was really good.

As a fan of the series, again my review is that it's pretty good, pretty funny and animation is really good, especially in some of the fight scenes, and very specfically a fight scene with Yor near the endish of the film was animated really well and defintley made it worth seeing in a actual cinema. Defintley a good adapation and just a fun time for fans of the series, so if the anime is similar to this quality then maybe I'll give it a shot.

One of my friends that came to see it with me had zero knoweldge of Spy X Family (and also doesn't really watch anime in general) and from their point of view they also kinda enjoyed it, so the movie does a somewhat good job at being enjoyable for both fans and non fans, though they also hated Anya, though I guess that not the movies fault.

Plot is what you'd expect from Spy X Family, though for being a movie it kinda feels directionless for a while and the ending kinda feels unfinished, though it's really enjoyable throughout, and it just kinda advances in stupidity until the end but that's why it's good. The ending especially is really enjoyable so you just kinda forget how silly the plot gets (and also that it just kinda abruptly ends) but for a anime orignal plot that can't have any impact on the main series, it's pretty good.

I did want to say a little bit that's basically just spoilers so feel free to skip this bit:

I feel they kinda push it a bit with the hiding of Yor & Loid's secret, because I know the whole point is Yor is super gullable etc, but Loid straight up flys a plane avoiding numerous missiles etc with Yor in the plane (sure Yor couldn't techincally see that but she isn't that stupid) and she doesn't question he can do that? or that he just crashes a plane on the warship? I don't think the series has ever pushed it quite that far... but still the stuff on the warship are still great though so I can forgive it but still kinda felt like pushing it a bit. Also final spoilery bit is that Yor & Loid run towards bulletts way too much, Yor straight up runs towards a anti aircraft gun and she's fine, though this is mostly nitpicking if I'm being honest.

If I had any major complaints it was that there's a good 5 - 10 minutes of this film

dedicated soley to Anya not needing to shit

and it really very very much was not needed and not something I wanted to see on the big cinema screen.... there is like a kinda cool scene that comes from it but like

I don't really care for humour that's just about shitting.

and if I'm being honest that was the only part of the film I didn't like.

Loid & Yor have some pretty cute moments, and they both have some cool fight scenes. It's a pretty funny film, though there were only a few times I really had a actual out loud laugh, it's more of a frequent smile kinda funny. But if I'm being honest I did laugh quite hard when the film started and the cinema I was at just cut off the subtitles becuase they had it set to the wrong aspect ratio, so all of the explanation of the basic plot for people who hadn't seen the series was just gone, so my friend who knew nothing of the series had to go through 50% of the film without actually knowing anything about what was happening.

Overall, really fun watch, well animated etc, worth seeing in the cinema if you can.
