The Prestige (2006): I think this is his Masterpiece. It's THEE movie that showcases all of his best talents and skill as a director and I don't think he'll ever top it. The Ending is also one of my favorites, Watching Batman shoot the sap who butchered Wolverine is such a satisfying moment for me. I always wanna watch it again the minute I finish it. It's a Top 10 best movies of all time for me.
Inception (2010): I think this is Nolan's most entertaining flick and second best directed film he's ever made. It's the only film he's made where he's managed to not only shoot decent action scenes but some damn great ones. I think it's overall his most well rounded film.
Memento (2000): The genius of this flick is undeniable and they way it unfolds just gets you hooked once the ball starts rolling. i also love the soundtrack to this movie which I think is very underrated.
Batman Begins (2005): I didn't love this movie the first time I saw it but no movie has grown on me with multiple viewings like this one has. If the action in this movie was better realized it'd be a perfect film.
The Dark Knight (2008): Overall a great movie with so much greatness in it but it falls apart near the end for me and feels rushed. This movie should've ended with Harvey turning into Two-Face. The action is pretty weak and Bale's performance is not nearly as good as it was in the first movie and neither is his appearance. Watching Ledger's performance and Oldman's performance as Gordon are the best things about this flick for me.
Insomnia (2002): Ever since I've seen I've seen the original, I haven't been able to watch this one. This was a decent slow burner as it was with it's cast making it better than it was but after watching the original, This became one of the worst remakes I've ever seen.
Interstellar (2014): The first half and a bit of this movie is fantastic but the rest of the movie is unwatchable to me. Still Matt Mc's performance is wonderful and the emotion, visuals and soundtrack of this flick is just something else.
The Dark Knight Rises (2012): Nolan's worst ambitious but soulless piece of crap of a movie with another outstanding soundtrack. The less I say about this flick, the better. Tom Hardy was great to watch perform even if it was a disappointing version of the character, it was still an amazing performance.
Haven't seen Dunkirk and I didn't care enough about the Following to rank it.
