I thought the first Transformers movie was good. The sequel was crap but most sequels are.

The old TMNT movies were pretty good, but I don't see how something like that could be made for today. They had that 80s appeal to them that you just can't get away with today.

I don't expect this new movie to be good, or bad, depending on what your expectations are, but if it's crap it's not going to ruin the classics of the early 90s for me, just like whatever crap cartoon they put out now doesn't ruin the old cheesy 1980s cartoon.
