Modern Warfare 3 Campaign Criticized for Short Length, Poor Quality and Large File Size

Players report Modern Warfare 3's 3-4 hour campaign is the shortest in Call of Duty history, while critics give it a 4 out of 10 due to the lack of innovative content. The massive 200GB download, largely assigned to Warzone maps and open-world zombie content, is deemed excessive despite Activision's justification.

Modern Warfare 3's campaign duration of 3-4 hours has been criticized for being the shortest in Call of Duty history.
Critics and players have judged the campaign to be of poor quality compared to past iterations of the game, with IGN scoring it 4/10.
Despite early access to the campaign, initial chatter online from players is trending negative for its quality, not just its length.
Modern Warfare 3 reportedly lacks any significant Call of Duty single player set pieces, which the series is known for, indicating a lack of innovation.
The game's enormous file size of up to 200GB has been attributed to new features including open-world Zombies and support for carrying forward items from Modern Warfare 2, as well as existing Warzone map files.
The Call of Duty HQ download manager, a roughly 50GB install, adds to the large install size and has been criticized for its complexity.
