Let's just say I would rather watch this again than Zombie Diaries, just terrible. Also, I didn't say I hated Diary of the Dead, just didn't think much of it for a new Zombie movie out. I was paying attention to the film thank you, I saw all the 'social commentary'.
One reason I prefered Land of the Dead was because of the scenes where the Zombies started to show signs of been able to do things for themselves, teamwork and so on(started in Day of the Dead from what I remember), found that aspect of Land of the Dead memorable.
It's fine when the zombies were around on screen in DOTD, it was just the conversations/script between some of the characters that bugged me and the lead actress just annoyed the hell out of me.
