Well...I kinda agree with most of the negative comments about 'Alien: Covenant'. It is a gigantic missed opportunity. My biggest issue apart from the predictability and nonsensical script, was the disappointment of seeing 'Prometheus' mixed up with 'Alien'. 

'Prometheus' brought new thinking to the genre and left us at the end with the sole human survivor and the android flying off towards the planet of our 'creators' to find out why they had decided to eradicate us. Prometheus visually stunning as it was was let down by an awful script an dialog in particular. 

What I did like was the scene shown much in the trailer, a character trapped in concealed room as something happens to her colleague. It was a longer scene that was tense and exciting and I so wish the rest of the movie could have come close.

 

 It's technically good as always Ridley Scott is a visionary filmmaker, but is unable to turn a weak script into a good film.
