"First off, I had to decide which sequels actually surpassed their originals in quality and influence. But I had to reconcile myself to whether or not entries in long-running series; e.g., James Bond, etc. counted as sequels. I decided the answer was yes, but I had to rank them in order to their intrinsic relation to their originals. I had to exclude certain movies because I thought they were really just parts of the same film. I'll be perfectly willing to hear arguments to the contrary, seeing as how I included The Empire Strikes Back. I should address the exclusion of The Dark Knight: Heath Ledger's performance as the Joker aside, there's no way that The Dark Knight is better than Batman Begins. So now, in order of preference, and judged by (1) comparison to the original, (2) overall quality and influence, (3) relation to the original, and (4) quality & influence of the original, here are my choices for the 50 best sequels out there." - filmicability.blogspot.com
