I'm not much of a Trek fan, so I'll take you at your word about the status of things regarding the NextGen movies.
With the MCU, I think what does help keep things exciting is just the sheer variety of characters they've got to work with. Granted, for the bulk of the films Marvel Studios didn't have access to their A-listers (X-Man, Fantastic Four, and especially Spider-Man, who they only got towards the later end of the Infinity Saga), requiring them to dig into their B-list and C-list hero cast. With how long Marvel Comics has been in publishing comics, they've a huge bench of characters to pull from. Heck, I would have loved to have been a fly on the wall when they were working on what would become Phase 1 and it dawned on them that they had the movie rights to the majority of the iconic Avengers roster.
That they've been able to do roughly the same origin story for each of the heroes and still have the films be generally entertaining for broader audiences says something to the quality of the cast and crew. And even many of the casting choices that made people scratch their heads ("Mark Ruffalo as the Hulk? RDJr as Tony Stark? Isn't Chris Evans more of a comedic actor?" are some of the ones I remember hearing) have since proven to be solid choices.
Even then, the MCU wouldn't have done nearly as well without Kevin Feige at the helm. The man knows his stuff, and like you said has a sincere and abiding love for the lore of the Marvel Universe while at the same time not being unwilling to change things up as needed.
