It isn't Lego Star Wars films themselves that are bad.  Many are able to make LSW movies extremely well and add a twist to the story that makes it original.  Fancypants has done just that and so have some others.  Sadly, almost every single brickfilm with a Lego Star Wars theme nowadays has poor animation, an unoriginal and uninteresting story (mostly just clones shooting droids and people showing off their LSW collections) and it's almost as if you see one you've seen 'em all.  It's not LSW films themselves that are bad, you can make a great brickfilm set in the LSW universe with a great story, it's just so many today focus only on the Star Wars part of it rather than having a good character development and plot.
