I remember liking Tank Girl as a teen in the 1990s, but looking at it now, it's easy to see what a mess this film is. It's not an odd or even fully enjoyable mess, and it's only occasionally amusing. It can't be chalked up to inexperience or disinterest in the source material, qualities that tend to factor into the better comic book films; because Talalay was an experienced director at this point and did like the material. But by all accounts, there was a lot of studio interference with the film because up until this past decade, very few people knew what to do with comic books or graphic novels as source material. The film is live action, but it also has clips from the comic books and animation sequences.
Most post-apocalyptic films tend to have a timeless quality to them, no matter what decade they were made in. Tank Girl is so 90s it hurts. The situation that the film takes place in is timeless - where a comet hit Earth and it hasn't rained in 11 years, so water is high in demand and only a select few has access to it. But everything else is 90s. Considering that one of the first places I was introduced to Tank Girl was an article in Harper's Bazaar, the fashion magazine (yeah, I read this as a teen, what?), the film is very high on costume changes (IMDB counts 18 for Lori Petty as Tank Girl) and it's all very punk-grunge-pseudo-riot grrrl. Even The Rippers dress in 90s clothing (flannel shirts and t-shirts, one Ripper looks like a half-man-half-kangaroo member of Color Me Badd). It's funny that in the comic's revival in the mid-2000s by IDW Publishing, Tank Girl was drawn as wearing a lot of 1980s power suits because the reasoning was along the lines of "a lot of people still dress like Tank Girl from the 1990s, it's no longer edgy." The soundtrack, supervised by Courtney (Love, Love-Cobain, whatever she's calling herself now) is sort of a mix of good 90s music and music that never made it past that decade, along with some bizarre covers (like Devo covering Soundgarden's cover of Devo's "Girl U Want", or something).
Tank Girl is an overwhelmingly cartoon-y film. And yeah, Tank Girl is a cartoon character even in the comics, but on film it's ridiculous. The film just meanders. The sense of urgency towards saving the little girl that lived with Tank Girl is never there because of all the side missions that are jokes and costume changes. It would almost be a parody if the film could settle on anything whatsoever, other than being a valentine to Tank Girl as a fashion icon of sorts, and occasionally her other positive attributes; like being a good friend or being a loud-mouthed and brave woman.
The one thing that I will give the film is that for much of the film, Tank Girl and Jet Girl (Naomi Watts!) have realistically post-apocalyptic water shortage greasy hair. Do you know how rare that is in post-apocalyptic films? Although Tank Girl's makeup rarely smudges, even when being in a torture chamber for what seems like a couple of days.
