I watched the prequel first, Army of Thieves, which was actually pretty good.
I watched Army of Dead for just the one lock picking character, hoping he had a bigger role, and was sorely disappointed that I wasted as much time as I did.
I was on shrooms for the first movie, that might have biased my reception of it, but it was at least better than the second.
I thought Army of Thieves removed what I enjoy about heist movies (clever puzzle solving, regardless of how unrealistic it can get) and instead replaced it with random acts of CGI-generated safe mechanics animation. Was well made but ultimately unsatisfying.
