100000% disagree. Larger maps are almost always better, especially in a game based on DUNGEONS AND DRAGONS. This is not BG 1 or 2, nor is it Divinity Original SIn 3. It is Baldur's Gate 3, and I personally enjoy the take they have on it, giving us large, expansive maps.
Besides, have you ever actually looked at a map of the Sword Coast--the region Baldur's Gate actually is in? It is freakin HUGE man. Game is doing great with the map design so far, and I hope it stays that way.
In the game, it's actually pretty tiny. This is the area you have in the game (in-game map spoiler), and all the marked locations are but a couple feet away from each other.
