Well, I like virtually all the events, but I'd be glad to help!
Among the "general island events":
The day when villagers go honouring the dead
The barrel of babies
The old friends
The celebration day could be little more festive and fun

I like very much when we have the choice between two "answers":

In VV1:
The prodigy child (I prefer it in VV1 rather than in VV2)
The old drum
The suspicious monkey

In VV2:
The savage child
The fastest runner
The spyglass
The bump on the head (it's funny)
And, of course, the events that may help to increase the villagers skills, the tech points or the food!

Oh! I like the others but it would be too long and I don't see events that I really don't like
