Everyone loves (or should love) a happy ending.

The Ewoks aren't so great at taking out those stormtroopers, though. For the first half of the battle they're pretty hopeless. Then they get their act together - and the help of a certain Wookie doesn't hurt either - and, as you say, the use their surroundings to their advantage.

I love it unashamedly. I still laugh at their antics and I still feel sad when that Ewok gets killed by the scout walker. Unlike some, though, I don't watch the forest battle and think "Oh, if only this was gritty like the battle on Hoth"; I enjoy it for what it is and have never felt that one battle scene is better or worse than the other.
