TV and movies have gone through their "loudness" phase, like the music industry did. As people (and venues) gain access to more advanced (and louder) equipment that can pull off higher decibels without losing too much clarity, there's a built-in expectation of audiences wanting "more" out of said equipment. Sound can be a bit like graphics, in that it's difficult to mix something that works equally well on all types of setups and configurations. The fact also still remains that a lot of people still only use the TVs built-in speakers for shows and movies, and while there have been strides in this department in the past decade or so, it doesn't compare to even the cheaper soundbars with a small subwoofer. TCL have among the more impressive out-of-the box TV speakers I've tried, and often at a decent prices, which is great news for those who want decent quality sound and image without going bankrupt.
Personally, I had to made a lot of adjustments to my setup to make dialogue more distinct without ruining balance, but I've gotten it to a good level now. Most setups with a proper front center speaker have less issues. One of the coolest solutions I've seen and heard is Bravia Home Theater systems using a Bravia TV as the center speaker to underscore dialogue (mind you, only newer TV sets have this feature), while the speakers do the rest of the heavy lifting, it's a rather unique approach (but a high-end center speaker will work better). I have an 85" Bravia 9, so it can be used this way, but I don't have the Bravia Home Theater system, so that's a no-go for me (I have a Harman Kardon system).
