The strong points of the film: Excellent production design, excellent costumes, excellent acting and excellent music. All combine to an esthetic whole which is much better than the sum of its parts.
The storyline is similar to one of the HG Wells novels, especially the Time Machine. But in this particular instance, the Time Machine is only able to bring someone a few years into the past. It is a limitation which encapsulates the entire plot, as there are several limitations put upon the film because of its low budget. Set in a Great Gatsby-like setting in the early 1920's, the film could easily have been one of HG's lesser-known stories.
Fortunately for this reviewer, the Director is savvy enough to understand her limitations, and to keep the film utterly under control for the entire length of time it takes to unravel the mystery that is set up in the opening scene, when an old man arrives in the middle of a garden party and begins the education of the guests in the physics of the 4th Dimension.
As the plot progresses, a young genius named Steven is beside himself with a mission to right a wrong that happened in his childhood, and is obsessed with finding a method to return to the past to do so. We suspend our disbelief at his feeble but well-intentioned attempts, and when one of the experiments backfires, we wonder if Steven will give in to his demons and descend into madness. It almost happens--if it were not for "the love of a good woman".
So that there are no spoilers in this review, I will summarize by saying that there is a final resolution which neither disappoints nor does it fail to engage our deeper intellect. Since I encourage anyone tired of the mall-screen movies of the 2000's, (with their overblown heroes and ridiculously unrealistic plots and absurd bombastic gun combat and fight scenes), to take a breath and let themselves be drawn into a meditative state as they sail down a lazy river and be contented with the calm, thoughtful work of art that was so effectively made into this film.
