It would be nice if this was some bait-and-switch, but this could also just be The Cleveland Show.
The Cleveland Show was actually pretty good, at least, after its first season, which was - and I say this as someone who likes the show - just terrible through and through. Out of the full 21 episodes in the first season, there's only 1 that's at all worth watching.
But by season 2 the show was starting to find its footing, and seasons 3 and 4 are genuinely good. Of course, it never reached American Dad! levels, but it did carve out its own identity by the end, and it was far better than it should have been.
If this manages to follow a similar trajectory, then it might be a pretty good show in the end, but much like with The Cleveland Show being unable to escape the shadow of Family Guy, I think that no matter how good it is, it'll always be too easy for people to dismiss it as a Rick and Morty clone. Heck, it took American Dad! about a decade before people outside of its hardcore fans to appreciate it and see it as more than just Family Guy-lite, so I wouldn't expect this to be any different.
And this trailer doesn't do it any favors either. It looks like Rick and Morty in all but name, while still managing to be less appealing on first glance. Of course, I'm sure if the show is successful enough, much like Cleveland and AD! it will become its own thing, but it'll probably rough at the start. And it has to be given enough time to figure out what sets it apart from Rick and Morty. Hopefully Hulu will give it a few seasons to do that.
