I can buy Clark being too frazzled or otherwise unable to locate Martha himself just fine, but, given that he can hear the Bat-comm channel, I'm unclear as to why he didn't save her once Alfred deduced her location.
Now, TF2 was critically and internet-ally reviled. Did they change anything for 3? Not really. And look how much more it made. TF4 was even more reviled than 2, but it did just a smidge less than its predecessor. And they're not changing #$%. They're actually doubling down with an entire new franchise of movies and spin-offs. Money talks.
Actually,
Transformers 3 made 50m less domestically than
TF2 despite the 3D surcharge, and
TF4 made 110m domestically less than
that. It's not that fewer Americans aren't going to see more horrible
Transformers movies, because they have, it's that overseas audiences, especially in China, have been going in growing numbers - and even then,
TF4, with all its pandering to Chinese audiences, made 100m less worldwide than
TF3. Meanwhile,
Deadpool will probably wind up with a bigger domestic take than
BvS, despite a much smaller budget and no 3D surchages.
As someone upthread said - sorry, I forget who - these franchise machines are so big and self-perpetuating it takes a big loss to derail them, and neither the
TF franchise nor the Snyderverse have had a big loss yet. However, in all probability, neither of the Snyderverse movies have been as big hits, budget-to-profit-wise, as the
TF series has been. (Also, amusingly, the first
Transformers beats
BvS by 17 points on Metacritic.)
