Summary: Alice is a major masterpiece.

Some details:
I. Time-travel
-- I am very critical when it comes to time-travel stories. The writers of Alice handled this very well with just 16 episodes. They backed it with current science and theories and less on artistic freedom. They also handled well the grandfather paradox.

Were there loopholes in the time-travel? At first, it appears so but after watching the whole series there is none. In the finale episode, many would probably think there were a lot of loopholes but I beg to differ, there were none as far as the theories and science used by the series they did this one well.

II. Acting
-- The acting of everyone were superb. From the comedy to seriousness, from the love triangle to family love, and from the future to the past to the present. I have no idea the sequence of filming you did--all past scenes first for example, or was it mixed--but everything fit perfectly.

III. Music
-- The background music were in the right place and at the right time. Not too soon, not too long, and definitely not in the wrong places. It was not used to elicit emotions, the music was there to add an additional layer to an already complex dynamics.

IV. Story
-- This is the most important part. The story is very deep and thought-provoking. It is a love story about a mother and her son. It is a love story about the son and a person who looks exactly like his mother. A love story about the son who was adopted and grew up with another family. It is a story about camaraderie. And it is also a story about time-travel and the repercussions and morals of it.

Having weaved all these different stories to form one grand story is not an easy thing to do in a 16-episode series. This is usually possible in a novel or comics but the writers of "Alice" and the director were able to pull it off. It started with love and ended with love.

Time has no beginning and no end but people do.
