Pros:

Good concept
Can be fun dying in unexpected ways.
Good for goofing off.

Cons:

Seems like they forgot to add finishing touches. 
It feels very empty. 
Some parts are ridiculously hard.
Bots are horrible and useless.

Conclusion:

If you just want to goof off and die repeatedly then this is the campaign for you. But if you enjoy a visually entertaining campaign then don't bother. Good concept but poor execution.
