If you compare this four hour TV mini-series to the twelve hour "Titanic: Blood and Steel" series, which also came out in 2012, then this shorter series is more enjoyable. And even with a much smaller budget, they accomplished a much more captivating and entertaining series. And one that is not actually a drag to sit through.
The 2012 "Titanic" series focus on the ship and the stories of the passengers, which is what the audience wants to see. Unlike the twelve hours series of political drama and shipyard problems.
The acting in this series was good and they had some good talents on the cast list.
I will say that the practical effects and special effects team managed to pull off the effects quite amazingly. And the visuals do play a big part in a drama about the Titanic.
The costume and props department also did their job quite well, fleshing out the atmosphere nicely.
If you have an interest in the Titanic then you should take the time to sit down and watch this 2012 TV mini-series, because it is actually quite entertaining and good.
