Through my course of anime obsession, I've grown to love anything and everything Gundam. Though, there have been a series or two I've strayed away from (SEED and TurnA). Gundam F91 was once in the category. Being a whole series condensed into just one movie did not fancy my interests, not to mention it looked cheesy compared to the rest of the UC era. Finally after picking up the first few volumes of Crossbone Gundam manga, I knew I'd have to see the movie. It turns out, it was pretty good for what it is.
Story(***): Out of 5 because it is fairly intriguing, but nothing new. One does tire of the same old plot of a civilian getting into a Gundam, showing Newtype abilities, and being thrown into the chaos that's happening around them. Nonetheless, it does get the extra push because it is slightly different, and the original scenario does set a great backbone for the rest of the movie. Also, the character's individual stories were fast moving (due to time limits), but you do begin to feel for them.
Animation(*****): If Neon Genesis came out in 1996, and this predates it by 5 years, it looks spectacular. The mobile suits look great and the characters hold true to the gundam style. What I truly enjoyed are all the minor details: The F91's fins opening as it launches, minute strafe thrusts as mobiles suits dock, snow and rain, debris of everything you can imagine pouring out of a space colony breach... it's all there.
Sound(*****): I do not believe, in a single Gundam series--past and present--have I heard such details of battle. Again, it's small things like bullets ricocheting off of armor, individual rocks moving, small scrapes from mobile suits landing on metal carrier decks, etc. Also, the music is second only to Char's Counter Attack. You gotta love "Eternal Wind", and the "Imperial March"-esquire background score.
My biggest gripe is how short it is. This is perfect material for a 6 OVA series. Had it been a little longer, we'd see more of the villain's background, and some nicer fights with Seabook facing off against Crossbone aces.
There's a lot of drama, a lot of good flashiness, some amazing sound, and a good deal of light hearted humor from the would-be-heroes. So, I suggest definitely giving this movie a try. As always with Gundam anime, you're going to want to start from the beginning and not here.
