Transformers

Optimus Prime takes like 10 seconds to transform.
In the past, it used to be just 'kuscch krussh kooo krsuch' and Optimus Prime would be trailer truck to robot. That's probably no more than 3 seconds.
Now in the new movie...its like.. 'Kruschh Kuschh kroo weee ziiiwoo krsucxs hjurt wewee ziiiii...' It takes like more than 10 seconds.
Isn't that like a major handicap. If I was Megatron I'll just blow Optimus Prime's ass to hell while he's transforming.
