so i just got out of an x-files marathon on the space network celebrating the series revival and there is something i noticed about those old episodes (from before molder left) and that is that they have aged very very well. sure the the monster costumes in some episodes are a little tacky but they hide it well with out being obvious that there hiding its flaws. and sometimes molder and scully can make odd choices for the sake of the story. like moulder choosing to use that sewer grate to cut that worm man in half instead using the gun they showed that he had but for some reason he put away, this is over shadowed by the overall presentation these scenes however.
to the series credit its comedy still holds up and they dont overdose on it. also the dont over explain things if something is better left un explained there not afraid to say the characters dont know and when the do explain things its short sweat and makes sense in that universe.
all in all its still a well done series and although it has its flaws there quite minor and often made up for or hidden. infact the only reason i noticed the flaws above is because i tend analyze shows i watch. people who dont do that definantly wont notice these things and people who do like me wont care the episodes were still very good and well written. as well the flaws in the series are no where near as glaring or as bad as recent clones of there series so i have to say the x-files despite its age its still the top of its genre.
