For a sci-fi movie with almost no special effects nor futuristic scenes it's still an entertaining movie worth at least a watch. There are some existential questions, not necessarily with answers, but that makes the movie interesting. Are we alone or most likely is there another civilisation? Sometimes it was a bit slow and the character of Dr. Isaac Bruno played by Patrick J. Adams is not particulary a pleasant character to watch but the story is what makes Clara a good sci-fi movie. The acting was okay, nothing special nor terrible. Clara is an easy movie to watch, nothing too complicated.
