I play most of the TT Lego games, but I really don't like the voice acting and the trend to make it more and more 'cinematic'. I preferred the miming and visual gags.
I think that was funnier than the kid-friendly dialogue we get. Either that, or we get audio clips straight from the movie like Lego Avengers, which just looks really odd. Then they have really long cutscenes that do nothing but recreate the movie. It has an uncanny valley effect, when Lego should be spoofing the source material and should just be lighthearted and fun.
Also, some of the clips are used in really weird ways: I remember playing as Scarlet Witch and she just mutters "You're a madman" every minute or so for no reason! And then her mortal scream from the film is played every time she uses her special power, gets a bit much.
Then again, maybe I'm only saying that because I grew up with the originals!
