In the years since, I have trouble sitting all the way through any of the prequels. TPM is probably my favorite, because I think it best captured some of the original spirit and fun of Star Wars. Sure, it has a pretty bad child actor, an annoying cartoon rabbit, and seems to be packed full of plot holes and poor writing, but it none the less had a sense of discovery, and fun moments.

I too enjoy TMP the most of the there. The reason is very simple. The older Anakin in ATOC and RTOS is just unbearable. Yes the young Anakin is annoying (due to bad acting mostly), but at least he is written as a nice character (helpful, selfless etc.). TPM is essentially still an adventure. On the other hand, Anakin in ATOC and RTOS is specifically written to be a disgusting character (selfish, ungrateful, hypocritical, short-tempered, whiny, stupid etc.). I just can't enjoy a film with that kind of main character. It is not an adventure any more but a bad soap opera centred around this troubled character.
