Flawed as it may be, TPM had a magic all its own, and it still makes me smile.
I remember going into the theatre and, yes, being somewhat underwhelmed by the movie itself.
But as I walked out and started commenting the film with a friend, I realised something that to me is the true magic of that movie: at no point during the film did I question the reality of what I was seeing.
I was so engrossed by the story and the action that I never stepped out of the experience and went "whoa, how did they animate all those robots?".
The underwater sequence was the only one that threw me off, but beyond that, I was just seeing other worlds.
Anyway, back to TFA, I find the showcased aliens somewhat lacklustre and uninspired.
