Pro Filters
A unique feature of Flight is something that the author calls filters. Filters are functions which can be executed before and after any other function and can change the parameters and the output of said function.
This feature is used instead of hooks which in other frameworks are used to execute code into different parts of the application's life-cycle.
Cons
Con Small community
FuelPHP has a pretty small community compared to other alternatives. This means that there are not many resources and guides for it out there, but on the other hand, it's easier to get help from the core team of developers that are working on Fuel.
Con Cannot use ArrayAccess
The fact that it uses static methods means that it's impossible for Flight to make use of ArrayAccess, which in turns means that it cannot inject dependencies easily.
