Cons
Con Recommendation engine is not great
It rarely hits that feeling of "YES! So glad it recommended me that movie for how I'm feeling now."
Con Not great support for non-english shows
Will only show content that has english titles. So even though the show you are looking for can have all the metadata with name, posters descriptions etc on "source" portals it will not appear on trakt unless it has english metadata to come with it.
Con Adding new shows/movies can be proven tricky
In order to add new shows you often need to jump through hoops via different sites (which differ for movies and tv shows).
The shows MUST have english title to be added at all.
