LEGO Movie is both a perfect continuation of the series and a breath of fresh air in terms of the graphic level and quality as well as mixture of music, humor, snarkiness, and entertainment. It is perhaps the best game in the series so far, and that includes all of the LEGO titles for console!
In the final analysis the game ended up offering an equal measure of entertainment across the entire age spectrum - and considering that the ability to appeal and maintain appeal for age groups over 17 has often been a challenge for the game series -- considering the different game play focus for the different age ranges, this is nothing short of amazing.
The game offers what appears to be, on the surface, around 20 hours of entertainment in terms of the Single Player Story (Campaign) Mode - but when you factor in the Free Play Mode, the plethora of collection items, as well as a challenging group of Achievements / Trophies, what you end up with is a game offering closer to 50 hours of entertainment, and that makes it a bargain as well as a pleasure.
One interesting observation in terms of the content and post-story content is the fact that the Collections and various traditional objects (like the Gold and Red Bricks) have become a much more obvious and accessible element in the game since the previous series and its three generations established the games.
All in all this is a must play for any fan of the LEGO series - past or present.
