Wonder why this decent ordinary flick is so highly rated and award worthy?

Rating: 4/10 (10 March 2018)

I watched this movie this week. This movie has won many key awards in oscars and golden globe ! I wonder why it has won many awards.
Another way to look at is the decline of quality movies in the last few years.
Coming to the movie itself, there are some good acting by all the lead players Sally, Richard and Michael.
Movie is shot quite retro and production values are top notch.
But, certainly not the best picture or director of 2018. I would consider it as an ordinary decent movie with a simple love story.
Only striking element to this movie is the titular character of the aqua-man itself. The Sci-Fi is top class and ingeniously conceived.
Other than this, its an overrated, over-hyped simple sci-fi love story.
It also looks like all the critic have taken this chance to felicitate this director for all his works in the past. I reckon its a weird way of assessing a movie.
