I watched Terminator 3: rise of the Machines (2003).
This is not a great film but it is not quite as bad as many people say.
Older John Connor is miscast and played incorrectly. He should not have been so detached and ironic.
This was the first of the franchises which was ruined by sequels which were in awe of the originals and therefore could not take themselves seriously and instead come across as sort of parodies of the originals. Too much fan service and winks at the audience.
Many such cases now.
