To be brutally honest, DLP is lacking in a lot of areas, especially when compared to other parks around the world. Even compared to Hong Kong, which has the lowest attendance out of all Disney parks (not including studios, or or none kingdom parks).
There is a complete lack of shows, attractions and character interactions. If you go during off-peak time, then there is literally no shows for you. For example, in February there will only be the 25th Anniversary show and nothing else. Whilst other parks reduce the frequency of shows during off peak, Paris seems to be the only park that completely stops pretty much everything and goes barebones during this period (which if funny, when they want to increase park attendance...).
I am hoping that things will get significantly better over the coming years now that Disney fully own the park.
