It's well liked by critics (88% on metacritic) and the audience (very positive on steam). Your opinion is an outlier. Let other people enjoy things.

It doesn't require multiple playthroughs. The game's chapters are just structured in a weird way. Each "playthrough" that's required has a different perspective and/or story than the last one.

Even if you consider each chapter a "playthrough", then each of those is just a few hours.
