Pros and cons
Another thread here asks the question "Brilliant or filth?" Well, "Lawn Dogs" is somewhere in between, but shoots for the former.
It's a drama with a satirical edge that has everything necessary for a great movie, but then fumbles a bit in execution. For instance, the key sequences where Trent (Rockwell) and Devon (Mischa) start to develop a friendship feel forced (I'm not talking about their initial meetings where Trent wisely encourages her to go away). The script needed tweaked with maybe some ad-libbing, but SOMETHING needed done to make these important scenes work better. As it is they’re at best serviceable and at worst unconvincing.
If you can get past that glaring flaw (and a couple cavils), there’s a lot of good here, even a little greatness. One critic -- Roger Ebert -- denounced the film on the grounds that it didn’t know what its message was. Really? It has about three main points and they come across loud and clear (don't read further if you haven't seen the movie):
1. A man and a girl can develop a genuine friendship in a brother/sister or father/daughter sense and there's nothing perverse about it.
2. But the adult has to use common sense so that their relationship isn't (1) misinterpreted or (2) slandered by enemies.
3. People can be materially wealthy and socially relevant, but morally bankrupt -- hypocritical, arrogant, fake, discriminatory, etc. People can also be impoverished and reclusive, but have hearts of gold.
There are of course additional gems to mine, noted in other threads, but these bits are linked to one of the three subtexts above, usually #3. For instance, the contrasting ways the inhabitants at Camelot Gardens regard Brett as opposed to Trent (Rockwell).
