I enjoy it. I find the games entertaining.
I can make a safe bet that you're not finding it entertaining for the gameplay. You might as well just buy the LEGO sets since you'd get far more out of them.
They're based on themes/franchises I enjoy, and they don't take themselves seriously. I can have a laugh while playing, and I can have fun playing it with a friend too.
Co-operative is the only reason I can see anybody enjoying these games, but then the quality of gameplay is irrelevant since you're having fun because you're sharing the time with somebody else, not because the game is in any way more entertaining than the person sitting next to you.
I find the that comedy of the cutscenes has decreased over the years. They're trying too hard.
And for most of their games, which are mostly based off of Movies, I don't need it to be an in-depth accurate recreation of the film. I've seen the film and can buy the official Movie Game.
I have no problem with the fact the movie games are exaggerated and humorous retellings. That fits the LEGO theme. Except the Official Movie Game.
The LEGO Movie Videogame is the most disrespectful thing I've ever had the shame of playing. It completely and ironically misses the entire point of the movie (to inspire creation, independence and self-confidence), and even goes so far as to cut chunks out of the source material that make light of this point. It's lazy, poorly designed, highly broken, and the game does not trust you ever to think about what you want to do. If you sit around for even a second, it will give you some irrelevant hint. There's no challenge, no reason.
So if TT is offering me a Lego version with silly gameplay where I walk through the game doing simple actions, that's fine.
I don't need deep gameplay for every single game I play. This is one of those light games that I find fun and look forward to playing. Doesn't matter if it doesn't change the gameplay up much, since I'm buying the game for the gameplay it already has.
That's not how the human brain works. The very short version of this lesson is that humans are pattern-seeking machines, because our brains are lazy and hate effort. We love patterns because we can store them away and use them to do less work in the future. The reason why challenging games are fun is because they keep presenting these patterns to us, and our brain loves to keep devouring them. TT Game's patterns are running, punching/shooting and occasionally some timing or memory matching. There's nothing incredible there. It's all been done better somewhere else.
You like the game for its graphics, its "comedy" and possibly other reasons unrelated to gameplay. I don't mean to imply you're wrong for liking them; if you enjoy these games, that's okay by me.
My problem is that I feel that we need to stop calling these "good games" since they offer nothing that a "good game" should offer. These developers have no respect for their audience. Kids are a lot smarter than people seem to assume, so that cannot be an excuse for piss-easy gameplay.
If TT actually embraced the values of LEGO: creativity, free expression, personal story and all that jazz, I'd be more than willing to support them. Unfortunately, right now all they're doing is repeating Crash Bandicoot, but adding a LEGO skin to it. It saddens me that LEGO would allow these games to exist, probably knowing full well this doesn't represent their product in a good light.
