FF7 was always filled with goofy stuff.
FF7 had many moments of levity meant to break up the oppressive feeling the game often gave, yeah. Filled with? Debatable.
The game however, had a dark tone to the overall experience. Loss and tragedy have a constant presence in the game. The whole last stretch of the game is a countdown to doomsday, with a giant meteor looming over the world, which dreary music replacing the optimistic adventurous overworld theme. Hell the game ends with the team diving into a tunnel to hell, and an ambiguous scene of cutting to 500 years later, without any hint to the party and the people of the world's fate.
The presentation of the Remake on the whole is completely transformed, the slums are a bright zone, full of light, cheery characters, and whimsical sidequests like finding fucking cats, picking flowers, and playing with children. The darkness, the grunge and grit of the sector 7 slums is COMPLETELY gone. Everything looks pristine, even the goddamn garbage piles.
The sector 5 slums are no longer the seedy underbelly they once were, the Honey Bee Inn, the prolific whorehouse is now putting on fucking musical shows run by a drag queen.
The trail of blood leading to a murdered president is replaced by a goofy trail of purple goo, to a president who gives a ridiculous speech who is stabbed by an apparition with no blood at all.
The creepy and iconic scene of the murdered Midgarzolom with the storm in the background is replaced by Sephiroth literally SAVING Cloud from the snake and flinging it onto the pike in a silly ass cutscene.
There are many such examples.
FF7 gave the impression of a world in decline, from the look and sound of each location to the things the people at those places would tell you. This "remake" series has lost that.
