Don't come up to me and say this film is overrated because it really isn't. I don't believe it deserves a spot as one of the Greatest Movies of all Time, that is fair. But this movie is a masterpiece on every level. I have but ONE, minor flaw with this movie. Aside from that, it is one of the closest things to perfect in recent memory. I HIGHLY recommend you see this movie if you have not.
The concept for this movie is amazing. It hurts my head to think about the logic of it but I'll be dammed if it isn't awesome. The story surrounding this concept is so well thought out and intricately designed that it is hard to dislike it. The ending for this movie is one of my personal favourite movie endings of all time. It is pure genius. If you dislike the movie, fine, I disagree with you heavily but fine. But if you think that ending is stupid, I actually hate you.
My one and really only flaw with this film is with some of the dialogue. As much as I love Christopher Nolan, his dialogue can occasionally be too exposition heavy. I 100% understand it was a necessary evil for this film but I still think it was overused.
There are a LOT of characters/actors in this movie so I will be brief on the subject. Leonardo DiCaprio was excellent in this movie as Cobb. Ellen Page was great as Ariande. Joseph Gordon-Levitt was excellent as Arthur. 'You mustn't be afraid to Dream a little bigger, darling!' basically sums up the greatness of Tom Hardy's performance as Eames. Marion Cotillard was great as Mal. Cillian Murphy was great as Fischer, as was Ken Wantanabe as rival Saito. Dileep Rao was good as Yusuf but his role was so minute for me to genuinely pay attention.
Every character in this movie served a key role to the story and all of them felt important. Even if people like Yusuf were sidelined for the leads, they still felt like they had a purpose.
The cinematography for this movie is amazing and there are countless shots in this film that took my breath away. The editing is also exceptional. The visual and practical effects are literally mind. Hans Zimmer's score in this movie is phenomenal. This movie IS, a technical marvel.
It is a complex, riveting journey from minute one and I cannot stress enough how amazing this movie is and how much I recommend it. Please, if you have not, see this movie... but be prepared to pay attention. It is 2 1/2 Hours long but it felt like 90 minutes. It is a technical marvel and I'll rate Inception a flawless rating of 10 Totems out of 10.
