I was always partial to the Super Mario Bros quadrilogy NES remakes on the SNES in Super Mario All Stars.
In truth, I really love the Silent Hill 2 remake but it does drag on in places. I guess that is a part of the "modern audience" today's devs try to capture. I mean, imagine releasing a game today that is a remake of an all time classic, and the game today is ONLY 5 hours long? The modern audience would complain it's not long enough!!!
I for one just think that remakes should do justice to the original whilst improving aspects of gameplay for us today (much like the Dead Space remake did).
