iPhoto Soooo confusing!!

[Chuckstones]

I just can't get my head around iPhoto on my new imac!!

I transfered all my pics from my old pc. And pics I had on my ipad. And thought I had them all arranged nice and neatly in albums!
Even created folders for say holiday snaps so I have sub folders for different holidays!

But then there is the 'Events'. Which I just do not understand!
Can I disable this? It just seems to complicate matters.
For example. If I transfer pics from my ipad or iPhone to albums on my mac. I then notice that they all need sorting in events!

And as for 'smart albums'. I tried creating one for movies. Dropped some in there and nothing!! so I just stick with folders so as to try and keep everything tidy!

Maybe I'm a bit simple. But is there something I'm missing!!?!
If someone could explain in lay mans terms I would most appreciate it!
