They think they hate it because its "not like BTAS and the people who are making it are destroying it" and that ain't true. TB is meant to override the greatness that is BTAS and the people involve in TB not only love the show and are fans of it, but some worked on it (even TNBA).
The truth is: this show has a huge shadow on it: BTAS. Fans of BTAS think WB threw away BTAS and all its brillance that came from it, and that ain't the case. Shows like the rest of the DCAU (which TB is a DCAU) and animated realism from BTAS went into shows like today like X-Men: Evolution. Remember the cartoons before BTAS? How old and "grainy" they were, would you want that?
And BTAS nor the whole Timmverse aren't gone, you have those DVDs and they are remembered, like I said on how its animation inspired every show that came after it.
The truth is maybe that those TB-haters can't even let go or can't see that TB not only isn't , it doesn't have to be BTAS all over again. You can maybe say that there's nothing wrong except in their heads.
Since it debut the show has been getting mixed reviews, but we all know the truth: TB has the huge shadow of BTAS. And that's why people SAY they hate it. Some probably want TB to be like BTAS, and it doesn't have to be. Other are probably afraid that TB is replacing BTAS, and that ain't the case.
And people might think TB won't be dark to suit those fans, but except for the DTV which was dark, since its debut the show has become dark and maturing episode by episode.
A BTAS fan love this and so does me. Others too.
There is nothing wrong with this show. Just watch it and say to yourself: "It AIN'T replacing BTAS, it doesn't HAVE to be like BTAS, IT'S ITS OWN SHOW."
