You're right it is monkey see monkey do...
Its why Mattel partnered Paramount to put out an American Doll movie, just announced 2 weeks ago, trying to capture lighting in a bottle again with that Barbie market. Forgetting that they did a bunch of direct to TV movies about 20 years ago that didn't do very well.
Then of course you got Hasbro trying to revive their toy live action films after the disappointing last Transformers, with yet another Transformers film next year, and a future GI Joe movie. And I kid you not a Monopoly movie, plus a bunch of other game movies including a reboot of Clue which is suppose to come out from Disney's 20th Century Studio. And lets not forget a Furby movie and a Play-doh movie, I'm serious.
Yep they are certainly monkey see monkey do. They try to find scripts that match what other studios were successful at and it ends up failing for the most part, and all mediocre. They take no risks....
