The Hollywood Reporter's Maggie Lee reviewed the film, which is an ensemble romantic drama with storylines that involves three couples, homosexuality, flashbacks from 1999 to 1972 and a play within the movie. Here's a bit from the review:
Beautifully composed, warmly lit and shot in sultry colors, June is steeped in the nostalgia of memory and of '70s Thailand. Scenes of heart-aching poignancy are enhanced by the classical cello score and a mellow Thai oldie, but the film is also painfully slow and needlessly wordy.
From the art direction to subtitles of dates and time, it is obvious that Nathaporn admires Wong Kar Wai. The play is reminiscent of the look and feel of In the Mood for Love -- perhaps too reminiscent, to the point of being derivative.
Even as I slap blockquote coding around that excerpt, I'm only half reading it because I don't want to know too much more about this movie before I see it, hopefully when it opens the 6th World Film Festival of Bangkok.
