I like a variety of film types, but I generally prefer realistic ones. Hot Fuzz is not even remotely realistic, and if I were some kind of anal, emotionless reviewer (I've read things from many of those), I would slaughter the film for its inconsistencies.
But, I'm not. I'm a normal human who likes to laugh, and this movie makes me do just that...over and over and over. I have watched Hot Fuzz probably 10 times and I am STILL catching new little details that I missed before. If I could use one word to sum up what makes Hot Fuzz so good, it would be the fact that it is "CLEVER." Yes, the acting is pretty good, the filming is excellent, and the story is...if not probable, entertaining...but the film's coherence, irony, and subtle puns are where it really delivers.
A couple of things are needed to really enjoy this movie (provided you enjoy funny movies even when their premise is silly). The first is a good knowledge of British slang, and the second is subtitles, at least the first time around. Due to my choice to not use subtitles, I am still, as I said, catching tidbits here and there of dialogue, not to mention visuals. Once you can understand and comprehend what's being said, though, you'll love this film.
Since I hope we can all agree the movie isn't meant to be realistic, I'll just laughingly mention the few glaring flaws in common sense (which I believe were intentional). The final gun battle was hilarious. Nobody could aim well enough to hit the broad side of a barn, and the sheer scale of the battle was mere audacity. The ease with which Angel turned the other cops from being rude and dismissive (especially the detectives) to joining his side enthusiastically, in the face of their screaming Inspector, was quite ludicrous. And, of course, the entire premise of "killing people for the slightest possible construed offense" (such as Tiller, for planning to leave town and "share her horticultural expertise with other villages") was nonsensical. Yes, the film's ENTIRE PREMISE was a joke.
Did that make me scoff and roll my eyes? Not at all. I did wish there was a little more development of Angel turning the cops to join his cause, but otherwise, epic gun fight and silly central theme included, I thought the film was spectacular. Again, the clever dialogue and the intricate cohesiveness are what really give this a 5-star rating in my book. It's hard to verbally describe what I mean, but the way events and comments are timed, and the subtle background details that accompany them, work together like a puzzle or a fine clock. Quotes from early in the film are repeated later in a completely different context. One of my favorite details is the dual reference to "Aaron A. Aaronson"; watch the film and you'll see what I mean.
Irony also finds a strong use in the film, be it the subtle irony in each person's name (Angel is a near-flawless do-gooder, Butterman Jr. is obese, Tiller is a gardener, Hatcher delivers babies, etc.); the irony that each "action cop" stunt that Danny wishes to perform, he gets to later on; or the irony that Skinner is finally stopped by the only TRUE "accident" in the film (tripping over the toy truck). The screenwriters here were masters of clever tricks and I loved it.
What's more, the filming is delightful. I really like the style employed here, as in Shaun of the Dead, with fast montages of various simple actions leading from one regular-paced scene to the next (such as in Angel's journey, via trains and taxi, from London to Sandford, or his initial entry to his hotel room). Other film tricks that I enjoyed were fast compilations of various camera angles, such as when Doctor Hatcher pumps his shotgun during the gunfight, in which I counted 6 or 7 layered camera angles that actually made the action somewhat "slow-mo" as it contained a repeat of the same scene, all within the span of 2 seconds or so.
In summary, Hot Fuzz is a brilliant movie that reflects hours of careful planning, stunning acting and delivery, innovative and snappy filming, and of course a ludicrous, overly crazy plot that only adds to the fun rather than making the movie suck. I would highly recommend this movie to anyone who likes a good laugh, is not offended by profanity, and can handle considerable gore.
