Which is the most fun/balanced way to play the scenarios of LNOE?

I bought LNOE + Growing Hunger to play with my girlfriend. We love the feel of the game, but we feel the game is unbalanced. For example:
1) Defend the manor - She rapes me with the zombies
2) Defend the Townsfolk - I run aroung collecting Townsfolk and she does not kill even one of my heroes. All in heroes favor.
3) Burn it to the ground - I got my first gas tank when 6 turns were left and my second tank when 4 turns were left. Never even had a chance. I cant control how search items appear.
4) Escape in the truck - The only one we felt it was balanced and fun. This game was awesome. Drama until the last turn!
5) Die Zombie Die - Dull
6) Zombie Apocalypse - The same as defend the manor.

You can always use the dots system to balance the unbalanced scenarios. "Die, Zombies! Die!" is just dull i can't agree more. Reduce the time limit to make it more of a challenge for heroes. Too much time to kill 15 zombies. Or if you lay your hands on "Survival of the fittest" include Zombies with grave weapons for it to balance it out. Just some suggestions.
