I must admit that the concept here in this 2015 documentary was definitely interesting. And given my interest and fascination with the Titanic, of course I sat down to watch this documentary, though it wasn't before 2021 that I had the chance to do so.
Visually then I will say that "Drain the Titanic" was impressive. It was really astounding to see the CGI rendering of the majestic ship on the sea floor, and seeing the water removed and the wreckage shown in that detail. However, what really impressed me was the crystal clear underwater footage of the wreck.
This documentary was interesting to watch, albeit a bit repetitive of the usage of CGI rendering. But it was definitely a good watch, and there were some interesting bits of facts being showcased. And the theory of the ship breaking apart deep underwater is really interesting and does make sense in terms of the spread of debris.
While "Drain the Titanic" was not the most phenomenal of documentaries that I have seen, it definitely is worth a watch, especially if you are interested in what has happened to the wreck laying on the bottom of the Atlantic Ocean.
My rating of "Drain the Titanic" settles on a six out of ten stars.
