two boys. a hotel. summer. a gesture. two different worlds. and a meeting. at first sigh, a movie about nothing. only broken solitude of a boy out of social circle. and a short dialog with a stranger who represents more than part of a fascination. like many short films, Vattnet is only a drop. or seed. or crumb from a large picture. but its message is profound. not only about ambiguous definition of stranger, not about ambiguous feelings of a teenager but about a fact as root for life. because all is suggestion. drawing. and story created by look of a boy , as part of a flag. it is beautiful. this is only honest verdict. and delicate manner to introduce an ordinary theme not as exception but as slice of life.
