There are a few were overlooking.
Ironman - While the first season was cheesy (the scene of The Mandarin kicking Blizzard in the face for 'freezing his petunias' comes to mind) it only started getting awesome in it's season finale and then second season onwards.
Fantastic Four - Similar to Iron-man in that it sucked until lt's second season . Had a VERY awesome voice actor for Doctor Doom who DIDN'T have a stupid 'fake accent'.
