Die Hard 3 is definitely the best in the series IMO, to throw that out there. ![]()
But yeah I do find I enjoy sequels more than the original quite often, but I suspect there's more to it than the quality of the film itself. For example a sequel has to concern itself less with establishing all the backstory and shit the original typically has to, and also because you're generally already a fan of the series you're going to be looking forward to a sequel more and will probably be more into it.
It's like how The Dark Knight is fantastic, but it's very much built on the foundation of Batman Begins which is a truly amazing standalone film. Take Batman Begins away and suddenly The Dark Knight doesn't have the same strength thanks to a lack of characterisation and backstory, yet the latter is arguably a more sharply produced film. In that specific example I can't actually choose one though because I love 'em both. ![]()
So my general stance is I either like the film or I don't. Too much headache trying to rank them!
