I usually overlook plot holes as well -- especially with movies since there is always the issue of time constraint with this form of story-telling medium. But I guess I went into this movie prepared to turn on my thinky-thoughts. :> (Unfortunately, it did decrease my enjoyment slightly because at the back of my mind, I was all, "Logic!fail~~~ \o\") Overall though, I did quite like it -- I really enjoy stories that play with the idea of reality vs. imaginary. :D
