I feel you. I first played the REmake and enjoyed it a lot but for some reason never got around to finishing it. Later on, I played the original and completed it, and liked it enough to play it again. Not sure why. I think part of it is the charming voice acting and over all B-horror movie feel of the original. Also, in my opinion the remake is actually harder. Sure, the original is clunkier with the tank controls and lack of certain QoL features, but the remake added crimson heads and other obstacles/events that increase the challenge significantly.
