As of now the mod is buggy and poorly optimized but that's common enough that I won't go on about it. The theme, setting, and voice acting are top-shelf. The writing is pretty good too. New critters, a perks system remeniscent more of Fallout: New Vegas (crossed with FO4), honestly this mod has the creators' love all over it. These are things that stay with a game or a mod after any amount of patching; what it needed to get right first it got right. And thank you GoG for making it so bloody easy to install. I'm afraid there are things they are less likely to fix, such as the eyestrain on many terminals and two very notable screens in the introduction section. Some of the UX is confusing such as backing out of terminal screens with Tab but having to leave the terminal with Enter. I hope they add the key to turn on/off the torch to the key binding in the menus. If you consider it an early access from any larger company you'll probably be ready for what to expect, but it was absolutely worth re-buying Fallout 4 on GoG to be part of this experience. I'm excited for it to go from release to polish.
