pretty captivating until the last 20 minutes
The last 15 minutes is where it went sour - cheaper sfx started to make themselves known - the big reveal was basically BS - sfx played a big part in making it all look cheap, but I also feel like script was also lacking.
8/10 for the first 75 minutes and 5/10 for the final 15.
Still - those first 75 minutes are worth watching - and it all really does make you want to see it till the end just to figure out wtf was going on.
Final score - 6/10 - could have been much better if the final 15 minutes were better, not only in terms of sfx but also in terms of the script.
