| Not great but better than the American alternative
I am not normally a fan of sentai movies or the team ups as they always seem to be rushed or forced and don't really add anything to the series and this was no exception.
That said it wasn't entirely a waste of time. The basic plot is that a villain from gogo v help the villains from timeranger and both sets of rangers (who don't get on) get thrown into the past and must work together to get home.
The special effects are not fantastic, but perfectly efficient. I particularly liked the fire at the beginning which the gogo v siblings help fight. The mecha battle at the end isn't very good especially when the gogo-mecha emerges from the time-mecha.
This Japanese film is better than the power rangers version which was rushed and probably only made because of contractual obligations. It bears absolutely no resemblance to the plot of the Japanese version. The nearest American equivalent is the movie madness episodes which borrow the rangers in the past scenarios.
