T1 is a classic
T2 was wondeful
T3 is meh
T4 is MEEEEEEEHHHHH I CAN WATCH THIS...MAYBE...TO THE END...PERHAPS...I THINK

I can't imagine a fifth film being anything thing but awful.

Perhaps they should have Michael Bay or Roland Emmerich direct it. They're pretty good at squeezing the most entertainment out of an all but non-existent, terrible plot via over the top explosions.
