Changes in adaptations are to be expected, but replacing an exotic, Japanese martial arts master with a fucking generic Michael Bay US military general that will be barking stock commands like "Just do it!", isn't my cuppa tea. It's reduced TMNT to a boring action movie cliche. Just like he reduced the colourful Transformers series in to a series of boring action movie cliches.
All the eccentricities and colour are being drained. Just.. fuck Michael Bay.
