Inception is falling pray to a revelation I had about Zach Snyder. Almost every single film Snyder has directed has been amazing (except Sucker Punch), but each film has an outstanding 'First Time Viewing.' Then slowly diminishes as the more times you view the film.
300 - Amazing first time viewing experience in theaters. Still a decent action film but the charm and glamour of the film has worn. Definitely not as enjoyable to watch anymore by far.
Watchmen - One of the best superhero films ever made and an outstanding film in general. Filled with deep stories and amazing characters and an ending for the ages (which I did not see coming). But seeing everything over and over it loses its edge quickly and the 3rd time I watched it the film lost a lot of the power it had. Excellent first time viewing though.
Dawn of the Dead and Legends are different to me and both are very enjoyable every time I watch them. Sucker Punch was a travesty.
The point I want to make about Nolan is that Inception is exactly like Snyder's first time viewing clause. While I think Inception (and 300/Watchmen) are all VERY solid, well made, beautiful films they all grow tiresome to watch after a while. None of them are bad films by ANY stretch, but they are films I personally don't want to watch anymore. Which is unfortunate about Inception because it is such an interesting and new visualization of 'dreams in movies' which I HATE. I hate dream sequences in films in almost every single scenario, but Inception isn't a 'dream sequence.'
I know this is all opinion and stuff, but man, i don't agree at all with this observation. Here's my experience of those films:
Dawn of the Dead: Thought it rocked from the first time I've seen it and seen it multiple times since (though it obviously doesn't even come close to the original).
300: Absolutely hated it the first time around and don't ever want to see it again. Same goes for Sucker Punch.
Watchmen: First time was the director's cut, which I thought was brilliant at times, but also quite boring for large parts. Second time was the ultimate cut, which I loved because the intercutting of the Freighter story gave the film a more episodic feeling, which helped its pacing a lot.
Inception: Was disappointed the first time around because I expected more from the whole concept of dream visualization. Dreams just don't work this way. They're a lot more random, surreal and fucked up. Second time I took it as a rather simple action movie with a unique premise and a little bit of drama thrown in for good measure and loved it.
TDK I fell in love with the first time I've seen it and it hasn't changed since. Same goes for BB and The Prestige to a lesser degree. Insomnia I thought was okay, but nothing too special. Memento I liked the idea, but thought the execution was boring. In all cases, multiple viewings didn't change my opinion at all.
