The quality of TFA will affect the quality of Eps. 8-9 just like TPM’s badness dragged down AOTC and ROTS. You need a solid foundation to make a great trilogy.
What do you mean it dragged down AOTC? AOTC surpassed TPM in terms of badness. Anakin in AOTC even by far surpassed Jar Jar from TPM in terms of annoyance.
