I did find it kind of funny that this and Star Trek Beyond both seem to have Lifeforce stuff in them.
I think replicating the formula is a mistake - but so is rushing into things and having no plan. The key is adopting the lessons learned in both broad strokes and strategically. A huge key is giving us films that in the beginning stand alone, with any connective content being secondary or tertiary to the main story. Studios, predictably, want Avengers money and thus rush to the team up or emphasize the shared world aspects without bothering to create compelling characters or standalone stories.
They didn't exactly rush into this. This whole Dark Universe thing was announced back in 2014 while Dracula Untold was in production. And they'd been kicking this idea around since like the 1999 Mummy. Marvel seems like less of the reason other studios came up with these things, and more just the reason they're finally pulling the trigger on them. I'm pretty sure the time between announcement and release is like the same as when Marvel announced everything they were doing leading up to The Avengers and the first Iron Man movie.
I don't see any problem with jumping right into the team up. We watch movies with groups of character or teams all the time without a series of films before telling us what everyone's deal is. We didn't need the Han Solo, Princess Leia, Obi-Wan Kenobi, and Darth Vader movies before Star Wars.
Only reason Marvel didn't jump right into an Avengers movies was money. They were a little studio when they started, and they only had the rights to characters nobody really knew or gave a shit about. They were counting on people enjoying the individual movies enough to artificially create something bigger when they all teamed up a few years later...and they just happened to luck out and have Iron Man become a hit.
